深圳海园一路隧道设计技术分析

随着我国城市经济的快速增长及人口的高度集中,城市隧道及地下工程的修建日益增多。鉴于城市隧道不同于山区一般隧道,该文在简单介绍城市隧道研究现状后,采用特征曲线法对隧道围岩加固机理进行了分析,以期在工程实践中能够准确、有针对性地采取措施提高隧道围岩自稳能力,保证结构安全和正常使用。结合工程实例,分析了深圳海园一路隧道的设计理念及设计方法、耐久性措施,可为以后相关工程提供技术参考。

Analysis on Design Technology of Shenzhen Haiyuan Road (1st) Tunnel

With the rapid growth of urban economy and a high concentration of the population in China,the construction of urban tunnel and underground engineering is increasing.For the urban tunnels different from the general mountain tunnels,this article briefly introduces the study status of urban tunnel,and uses the characteristic curve method to analyze the reinforcement mechanism of tunnel surrounding rock in order to exactly and especially take the measures to improve the self-stability ability of tunnel surrounding rock,and to guarantee the structure safety and normal service.Combined with the engineering cases,this article analyzes the design concept,design method and durability measures of Shenzhen Haiyuan Road(1st) Tunnel,which can be referred for the similar projects.
