1 概况 共和新路高架工程12.4标位于彭浦立交桥的西侧,部分承台开挖深度达到5.5m左右,由于彭浦立交桥的承台为扩大基础,且其承台边距离新建承台边只有5米,为了确保彭浦立交桥的安全使用,我们对新建承台基坑采用SMW工法劲性水泥土搅拌桩围护。
1 Overview Gonghe New Road Elevating Project 12.4 is located on the west side of Pengpu Overpass. Some of the caps have an excavation depth of about 5.5m. Since the caps of Pengpu Overpass are enlarged and the edge of the caps is only 5m away from the newly built caps In order to ensure the safe use of Pengpu overpass, we adopted the SMW method of strong soil cement mixing pile envelope for the new bearing platform foundation pit.
