摘要
青岛高新区全地下污水处理厂基坑支护工程,具有基坑开挖深、面积大,地下水位高,地层土质差,中粗砂层厚等特点,采用上部吹填淤泥层放坡、下部在前排桩后增加少量后排桩,形成双排灌注桩加锚杆支护的综合支护形式。重点介绍了基坑支护方案,通过现场基坑监测数据分析及工程实践效果,表明支护方案的合理可靠性。
The foundation excavation support for the underground sewage treatment plant in Qingdao high-tech district was featured by deep foundation excavation,large area,high water lever,poor soil strata,thick coarse sand layer,etc.A comprehensive support system of double-row bored piles plus anchor was adopted,whose upper part was slopes with reclamation silt and in the lower part,and some back piles were added behind the front piles.The support scheme is introduced in detail.The monitoring data and practice proved that the support scheme was reliable and reasonable.
