膨胀土场地基坑支护设计施工措施
Construction & Design Measures of Foundation Pit Supporting on Expansive Soil Site
摘要
Abstract
The hazard of expansive soil in Mengzi areas is one of the most serious regions in our country with higher occurrence frequency.Based on the knowledge and understanding the characteristics of the expansive soil and its distribution as well as the surrounding environment of the foundation pit,all factors including the reasonable value of mechanical parameters,the influence of the horizontal expansion force,deformation characteristics,and earth excavation,waterproof and drainage measures and monitoring measures are discussed during the design process of foundation pit supporting structure;it is approved that using pile and anchor supporting system is feasible in the deep foundation pit supporting design.It is of good stability,small deformation,lower investment and it is convinced to be the optimal solution under the multi-target evaluation;it can provide certain reference and guidance for design and construction of foundation pit supporting in expansive soil area.关键词
