为解决传统施工防水位测定方法存在的测定误差大、应用性能差的问题,提出基于抗力平衡的地下建筑结构施工防水位测定方法。根据地下建筑的设计结构搭建有限元分析模型,安装相关的传感器与测定设备;分析地下水的类型与作用原理,在构建的结构模型下,遵循抗力平衡原理计算地下建筑结构应力;根据建筑结构应力与抗力的分析结果,最终得出地下建筑结构施工防水位的测定结果。经过工程分析实验得出:与传统测定方法相比,设计测定方法的测定误差降低了约0.805 m,将其应用到施工项目中得出的施工质量有所提升。

In order to solve the problems of large error and poor application performance in traditional methods of measuring waterproof level,a method of measuring waterproof level of underground building structure construction based on resistance balance is proposed.According to the design structure of underground buildings,the finite element analysis model is built,and the relevant sensors and measuring equipment are installed. The type and action principle of groundwater are analyzed. In the structure model,the stress of underground building structure is calculated according to the principle of resistance balance. According to the analysis results of the stress and resistance of the building structure,the results of the measurement of the waterproof level of the underground building structure construction are obtained. The results of engineering analysis and experiment show that the error of design measurement method is reduced by about 0.805 m compared with the traditional method,and the construction quality obtained by applying it to construction project has been improved.
