软弱土层中不同基坑支护方案的分析

Analysis of different schemes for soft soil foundation pit in soft soil

结合具体工程实例,比较了在同一软弱土层地区采用不同的基坑支护方案的优劣。分析表明,水泥搅拌桩与土钉墙组合的支护结构型式比传统的排桩与内支撑组合的支护结构型式具有更大的优势,该支护结构与其它支护结构相比,具有明显的经济性和优越性。

Based on actual foundation pit supporting projects,different schemes of foundation pit supporting are introduced in the paper,the advantages and disadvantages of different foundation pit support schemes are compared in the same soft soil area,it shows that the composite retaining wall combined cement mixing pile with soil nailing has greater advantage than soil nailing wall in the soft soil foundation pit,it has obvious economy and superiority.
