摘要
桩锚-混凝土撑支护体系以其经济、抗侧刚度大且止水效果显著等特点,被广泛运用于基坑工程建设中。针对该支护体系的工程特性,选取南昌市某异形深基坑工程为例,对其支护形式和设计思路展开研究,并对桩锚-混凝土撑支护关键技术进行阐述。通过现场监测数据分析,验证这种支护形式在工程中具有较好的支护效果。
The pile-anchor-concrete bracing and supporting system is widely used in the construction of foundation pit with its features such as economical efficiency,excellent lateral stiffness and significant effect of water-sealing. Aiming at the engineering characteristics of the supporting system,a special deep excavation project in Nanchang has been selected as an example,and its supporting form and design ideas have been studied while the key technology of pile-anchor-concrete bracing and supporting system has been expounded. The field monitoring data has been analyzed to verify that this support form in the project has the preferable support effect.
