摘要
介绍南京市宁南地区地下隧道施工中选择拉森钢板桩支护的合理性,并对其设计方法和施工措施进行详细阐述,设计、施工思路有所创新,支撑体系采用圆木支撑有效地缩短工期,节约了成本;开挖方式采取阶梯式开挖,边挖边撑,这与支撑体系正常施工工序有所区别,在此工程中具有其适用性及可行性。通过对施工过程进行监控量测,证实了此种支护形式是安全、经济合理的,为今后类似工程施工提供参考。
In this article,it is introduced the rationality of selecting Larssen steel sheet pile support in constructing under ground tunnel,elaborated the methods of design and construction,which have new innovation,the support system can reduce erection time effectively by using log braces,and have cost saving;the excavation is done by multistep,digging the foundation pit as underlaying the log,it is different from the general support system,which has applicability and feasibility in this project.According to monitor the whole process of construction,it is proved that supporting form is safe,economic and rational,which can provide a reference for construction of similar projects in the future.
