An intelligent optimization algorithm of steel sheet pile foundation pit concrete thin seal technology

Abstract

In recent years, with the rapid development of foundation pit engineering, many technically complex foundation pit engineering projects have emerged. The scale and depth of foundation pit excavation are getting bigger and bigger, and the requirements are getting stricter. The safety and stability of the foundation pit will determine the success or failure of the foundation pit project, and it is very important for the smooth development of the entire foundation pit project. The purpose of this paper is to study an intelligent optimization algorithm of thin-seal concrete layer technology for sheet pile foundation pits. Taking the support project as an example, the steel sheet pile support is determined as the foundation pit support scheme. The finite element software is used for simulation analysis, and the construction conditions are simulated for the scheme at the same time, the construction scheme is formulated, and the simulation results are compared and analyzed with the on-site monitoring results. The results show that when the construction of the sealing layer concrete is completed, the displacement monitoring value of the steel sheet pile is not much different from the simulated value, and does not exceed the early warning value, which is within the error range.
