高速铁路路基沉降风险评估量化模型研究
Study on evaluation quantification model of high-speed railway subgrade settlement risk
摘要
Abstract
High-speed railways require a high degree of ride comfort. The subgrade as an important part of the railway line project, its stability is very important. Based on the grid management theory of railway infrastructure, this paper used the fuzzy logic reasoning method to obtain the evaluation model of high-speed railway subgrade settlement risk. In this paper, the possibility of settlement risk of high-speed railway subgrade was quantified, and the settlement position of roadbed is located within 200 meters, which can realize the fine management of high-speed railway subgrade settlement risk. Finally, this paper used the actual data of Lanxin high-speed rail, and a 200-meter grid monthly data to validate the example.关键词
