摘要:
水泥土桩复合土钉支护体系同时具有止水和基坑边壁支护双重作用,与普通土钉支护相比,可减小坑壁侧移,加大施工开挖速度,以及均匀土钉受力,改善环境影响.通过复合土钉受力变形机理的对比分析,研究了水泥土桩复合土钉支护体系中水泥土桩的基坑自立临空高度的提高机制、桩土摩擦传力机制、支护体系侧移曲线的整合机制以及基坑边壁优势滑裂面的前移机制,对完善此类支护体系施工过程中的侧移控制措施和加快施工进度具有一定的理论指导意义.
Abstract:
Compared with ordinary soil nail support, the cement-soil pile composite soil nail support system has the dual functions of water stop and foundation pit side wall support, which can reduce the lateral shift of the pit wall, increase the construction excavation speed, and uniformly affect the soil nail and improve the environmental impact. Through the comparative analysis of the stress deformation mechanism of composite soil nails, the mechanism of increasing the self-standing air height of cement soil piles, the frictional force transmission mechanism of pile soil, the integration mechanism of the side shift curve of the support system and the forward movement mechanism of the advantageous slip surface of the edge wall of the foundation pit were studied, which has certain theoretical guiding significance for improving the lateral shift control measures and accelerating the construction progress of such support systems.
