拉森钢板桩在太化基坑支护工程中的应用探讨

摘要

以太化新材料园区工程为例，对工程的水文地质条件进行了分析，确立了钢筋混凝土灌注排桩支护+深层搅拌水泥桩作止水帷幕与拉森钢板桩支护两种基坑支护方案，并对两者作了对比研究，指出拉森钢板桩方案可有效节约成本，缩短施工工期，确保施工安全。%Taking the Taihua new materials industrial park project as an example,this paper analyzed the engineering hydrogeology condition, determined two foundation pit support schemes making reinforced concrete bored piles support + deep mixing cement pile as water curtain and Larssen steel sheet pile support,and made comparative research on both,pointed out that Larsen steel sheet pile scheme could effectively save cost,shorten construction period,ensured the construction safety.
