摘　　要：结合长三角软土地区的深基坑支护工程实例,针对周边环境复杂、地质条件差、地下水位高的情况,采用“SMW工法桩+组合型钢(HC)支撑”的经济合理性、技术先进性、安全可靠性等进行分析评价,并对本工程的理论计算变形值与实际基坑监测动态数据相对比,确定了SMW工法桩与组合型钢支护相结合的方案在深厚软土地区的应用。Combined with the practical example of deep foundation pit support engineering in the Yangtze RiverDelta soft land area,in view of the complex surrounding environment,poor geological conditions and high ground-water level,the economic rationality,technical advance,safety and reliability of “SMW construction pile + compos-ite steel(HC) support” are analyzed and evaluated,and the theoretical calculation deformation value of this projectis compared with the actual monitoring dynamic data of foundation pit.The application of SMW construction pile+HC support in deep soft soil areas has been determined.
