Prospect of Infrastructure Construction under "Belt and Road" Initiative（“一带一路”的基础设施建设前景）

The process of how the "Belt and Road" Initiative was brought up is studied and the major opportunities that the "Belt and Road" Intiative brings to China are described in this paper. The "Belt and Road" Intiative is very prospective. The important role of the infrastructure construction in the "Belt and Road" Intiative is shown. Two examples of the infrastructure construction under the "Belt and Road" strategy, i.e., China Nepal India Trans Himalaya Corridor and Kra Isthmus Canal in Thailand, are introduced. Finally, the challenges that China will face in the infrastructure construction under the "Belt and Road" Intiative and the rational countermeasures are described.

Key Techniques for Construction of Sanyang Road Cross riverTunnel of Wuhan Rail Transit Line 7（武汉轨道交通7号线三阳路越江隧道施工关键技术）

The author focuse on the great challenges encountered during the tunneling process in the Wuhan Sanyang Road Tunnel, and the key techniques adopted to solve those problems. When tunneling in composite strata, engineers inevitably face problems such as inefficient excavation, excessive tool wear, excavation face instability and the risk of clogging. The TBM used in the project allows tool change under atmospheric pressure, which improves the efficiency of tool change and eliminated the risk of casualties during hyperbaric interventions. In terms of the tool wear and clogging, the authors propose technical solutions as follows: the optimization of the tool′s type and configuration, improvement of the central flushing system and chemical dissolution of clogging. The results indicate that through the countermeasures proposed, the tunneling efficiency can be improved effectively. They also reduce the cutter change frequency and eliminate the risk of TBM downtime. The technical achievements obtained in the construction of the Wuhan Sanyang Road Tunnel can provide technical reference for the construction of large diameter shield tunnels in composite strata in the future.

Innovation and Practice of Parallel Dual mode Slurry/EPB Shield Construction Technology and Freezing Cutterhead Opening Technology（并联式泥水/土压双模式盾构施工技术与冷冻刀盘开舱技术的创新与实践）

Two major concerns have been drawn in the process of shield construction: one is the difficulty in selecting a shield machine; the other is the high risk of opening for cutterhead changing. Based on the existing shield systems, a parallel dual mode shield with freezing cutterhead is developed by optimising internal structure and equipment and carrying the freezing device. The dual mode shield construction technology and freezing cutterhead technology are successfully carried out on project cases including Guangzhou Metro Line 9, Guangzhou Metro Line 21 and 220 kV Shijing Huanxi Electric Tunnel (Xiwan Road Shisha Road Section). The parallel dual mode slurry/EPB shield not only has the functions and advantages of slurry shield and EPB shield but also can switch into slurry/EPB mode for different strata and environments easily. Thus, it can achieve rapid shield tunneling. By combining the shield with the freezing system, the soil around cutterhead can be frozen to provide conditions for chamber opening under atmospheric condition. Meanwhile, it is also compatible with dual mode shield.

Representative Projects and Development Trend of Underwater Shield Tunnels in China（我国水下盾构隧道代表性工程与发展趋势）

In the 21st century, the underwater tunnels have advanced rapidly in China. A large number of projects, completed or ongoing, have greatly promoted the advancement of underwater shield tunnel technologies in China and in the world. The development history of the underwater tunnels in China is summarized, and the technical challenges and breakthroughs encountered and achieved during the construction of many tunnels are presented, as represented by Nanjing Yangtze River Tunnel and Shiziyang Tunnel of Guangzhou Shenzhen Hong Kong High speed Railway. The characteristics and challenges of some representative underwater tunnels during construction, including Road Railway Yangtze River Tunnel in Sanyang Road, Shiziyang Tunnel of Foshan Dongguan Intercity Railway, Yangtze River Tunnel of Suzhou Nantong UHV Power Transmission and Transformation Project; and projects to be constructed, such as Pearl River Estuary Tunnel of Shenzhen Maoming Railway, Shantou Bay Subsea Tunnel of Shantou Shanwei High speed Railway, and Nanjing Heyan Road Yangtze River Tunnel, are presented as well. The development trend of China′s underwater shield tunnels, including from single soft soil formation to complex soil formation, from large diameter to super large diameter, from medium water pressure to high and ultra high water pressure, from ordinary to special and unfavorable geological conditions, from seismic regions with moderate intensity to those with high intensity, and from single construction method to combination of multiple methods, are analyzed. It is pointed out that the technical fields still require further study and innovation, and the areas still require further enhancement and innovation, such as the norms, codes, designs, constructions, equipment, materials and management.

杭州狭长软土基坑支护侧移规律与解析预测方法研究

In order to reduce the influence of deep narrow foundation pit construction on adjacent properties in urban area in Hangzhou, the characteristics of the support wall lateral deflection are analyzed and the corresponding analytical prediction method is proposed. The support wall lateral deflections of the deep narrow foundation pits at Wenyi West Road, Qingchun Station, Qiutao Station, Xingtang Station and Qingnian Station in Hangzhou soft clay are monitored and compared with those of deep foundation pits in Zhejiang and deep narrow foundation pits in Shanghai, Taipei and Singapore. The results show that the maximum support wall lateral deflection of the foundation pit on Wenyi West Road, 0.20%He ~0.25%He, where He is the maximum excavation depth, is close to that in Shanghai(0.15%He~0.41% He), but is smaller than those in Zhejiang, Taipei and Singapore(0.27% He~0.62% He); which is related to the high tangential modulus of Hangzhou soil and small width of the foundation pit. The support wall lateral deflection of the narrow deep foundation pits in Hangzhou can be precisely predicted based on the representative stress strain relationship at site and the modified mobilisable strength design (MMSD) method.
