SMW工法与混凝土支撑在深基坑支护中的应用

摘要

In this paper,analysis on SMW construction combined with concrete bracing is conducted through an excavation bracing project in Zhangzhou.The monitoring data proved that the bracing method is applicable in sand layers.Moreover,SMW construction can be used as cutting off water system as well as vertical bracing structure,and combined with cross and arc bracing to provide a better bracing system than others in terms of construction period,economic,environment protection,etc,and as a result can be applied to deep excavation bracing.%本文以漳州某一工程基坑支护为例,对SMW工法和混凝土支撑的联合支护形式进行分析,结合现场的监测数据,说明这一形式在砂质地层的适用性。SMW工法作为竖向围护结构的同时又可作止水体系并结合对撑及圆弧支撑,在工期、经济、环保等方面都优于其他支护形式,可在类似的深基坑工程中进行推广、应用。
