摘　　要：本文结合漳州地区某深厚软土复杂地质工程的基坑工程实践,通过多种基坑支护方案的比选,采用了长短SMW工法桩+预应力扩孔锚索的支护方案。该支护体系利用SMW工法长桩与SMW工法短桩之间的协调作用,实现了基坑支护的安全性与经济性的统一,在一定程度上能避免材料的浪费并缩短工期。Based on the foundation pit engineering practice of a deep soft soil complex geological engineering in Zhangzhou area,through the comparison and selection of various foundation pit support schemes,the long and short SMW pile+pre-stressed anchor cable support scheme is adopted.The supporting system makes use of the coordination between SMW long pile and SMW short pile,realizes the unity of safety and economy of foundation pit support,avoids material waste and shortens the construction period to a certain extent.
