采用拉森钢板桩的深基坑支护设计

摘要

对具有较深淤泥层的9.6 m的深基坑支护形式进行研究分析,提出了采用拉森钢板桩为支护结构,内设三道钢支撑的设计方法,对比其他深基坑支护形式具有很好的经济效益,从而为深基坑的支护设计提供参考借鉴。%The study undertakes the research and analysis of the support form of the deep foundation pit with 9.6 m deep silt layer,points out the Larssen steel sheet pile should be adopted as the support structure and the triple steel support should be designed inside,and indicates it has better economic benefits by comparing the method with others,so as to provide the reference for the support design of the deep foundation pits.
