摘要
通过对比分析,阐述了在软土地区城市中心区深基坑多道支撑下,土方开挖过程中选择不同的施工技术对挖土进程、经济效益的影响有所不同。针对工程特点,创造性地采用钢板桩作为出土坡道的临时挡土墙,并利用对撑与出土坡道形成有效出土通道的方式进行土方开挖,可达到快速、安全、经济的效果。同时首道支撑兼作堆料平台,充分缓解了城市中心区现场用地紧张的现状,降低了工程造价。
Based on comparison analysis, this paper introduced the effect of different excavation methods of deep foundation excavation in soft soil with supports. According to the engineering characteristics, steel sheet pile was used as temporary retaining wall, brace and excavated way were used as affective passway for excavation. The first supports was used as stacking platform which can solve the problem of shortage of land and reduce the cost.
