摘要

摘要: 地下连续墙具有施工振动小、墙体刚度大、整体性好及施工速度快等优点,因而被广泛应用于深基坑开挖围护结构工程中。弧形地连墙属于空间板架结构,从经典薄壳理论着手,推导出静力平衡微分方程,提出了弧形地连墙侧位移计算的新方法。以南昌市红谷隧道东岸深基坑弧形地连墙为例,利用此新方法计算其侧位移,并与监测数据对比,探讨该方法的可行性和计算精度问题。结果表明：使用该方法来计算弧形地连墙的结果与监测结果在趋势上是一致的,且数值上相差不大,说明用这种方法来计算是可行的,并且计算跨中位置的侧位移比端部位置的更吻合实测值。

Abstract: Diaphgram wall has the advantages of small vibration, high stiffness, good integrity and fast construction speed, so it has been widely used in excavation retaining structures of deep foundation pit. Arc diaphragm wall belongs to space frame structures. Based on the classical shell theory, the differential equation of static equilibrium is deduced, and the new method for calculating the displacement of arc diaphragm wall is proposed. For the arc diaphragm wall of deep foundation pit at the east side of Nanchang Honggu tunnel, this new method is used to calculate its lateral displacement, and it is compared with the monitoring data. The feasibility and precision of the new method are investigated. The results show that the calculated values of the arc wall by this method has the same trend as the monitoring data, and the difference is just small. The proposed method is feasible , and the calculated results of the lateral displacement at the cross position is more consistent with the measured value.
