浅谈钢板桩围堰在跨河桥梁深基坑支护中受力分析

近几年,随着国内高速铁路和客运专线的飞速发展,为了满足跨高等级道路通行和跨主要河流的防洪及通航需要,大跨度连续梁在跨河、跨路中得到了广泛的应用。对石济客专5标段景德特大桥跨南运河连续梁主墩深基坑钢板围堰支护的受力进行了分析,并对该方案的可行性进行了检算,在实施过程中,充分验证了此施工方法的可行性和有效性。

Stress Analysis of the Deep Foundation Support of Bridge over River

In recent years,the rapid development of domestic high speed railway and passenger dedicated railway lines have been witnessed. To meet the demand of pass on high class road and flood prevention and navigation of main rivers,large span continuous bridge are widely used in bridges over rivers and roads. The paper analyzes the stress of deep foundation steel plate cofferdam support for main pillars of Jingdete Continuous Bridge over Nanyunhe Canal on Shijiazhuang-Jinan Passenger Dedicated Railways,and checks the feasibility of the scheme. And the feasibility and effect are verified in construction.
