深基坑钢板桩支护技术在施工中的受力分析

Stress Analysis of Steel Sheet Pile Support Technology for Deep Foundation Pit During Construction

以太行山高速公路漳河大桥深基坑钢板桩围堰施工为例,重点阐述了钢板桩围堰引孔施工方法,钢板桩围堰设计结构尺寸形式,钢板桩设计水土压力计算,不同工况下钢板桩最不利情况计算。通过对深基坑开挖全过程不同受力分析计算,保证了现场的施工安全,较好地完成了深基坑开挖工作,达到了预期效果。

Taking the construction of steel sheet pile cofferdam for the deep foundation pit of Zhanghe Bridge on Taihang Mountain Expressway as an example,this article focuses on the construction method of steel sheet pile cofferdam lead hole,the design structure size form of steel sheet pile cofferdam,the calculation of water and soil pressure for steel sheet pile design,and the calculation of the most unfavorable situation of steel sheet pile under different working conditions.By analyzing and calculating the different forces during the entire process of deep foundation pit excavation,the construction safety on site was ensured,and the deep foundation pit excavation work was successfully completed,achieving the expected results.
