| 摘 要： | 地下人防工程是世界各国城市建设中必须考虑的重要工程,但受工程地质条件、技术因素等多种因素的制约,人防工程的开挖稳定仍是目前研究所面临的主要难题.研究中采用数值模拟方法对基坑开挖方案、支护形式、本构关系和主要参数进行研究和初步设计,确定了初步设计参数,并通过工业性试验和工程监控,验证了数值计算在土钉设计中的可靠性,为基坑工程的支护设计提供了依据,且产生显著的经济效益.

| Abstract: | Air defense facilities are important projects in the urban construction around the world,however,the excavation stability of these projects has been troubled by complex geological conditions and technical restrictions and therefore remains a problem to be conquered.In my research,the method of numerical simulation is employed to study and preset the foundation pit excavation plan, way of timbering,frame-member relationship and some major parameters.Through industrial experiment and project supervision,the reliability of the numerical calculation in soil nail design has been confirmed,thus provides reference for the design of timbering plan for foundation pit projects and is to result in technical and economic profits. |
