铁路客运专线深厚黄土路基工后沉降数值计算模拟

客运专线因其实行客货分运而具有快速、安全的特点,越来越成为国内旅客运输的重要方式。为保证客运专线开通后按照设计速度运营后列车的安全性、平稳性和旅客的舒适性,对线路基础的工后沉降提出了更加严格的控制标准。因此有必要系统性地对客运专线路基的工后沉降进行理论上的研究。该文从客运专线铁路工程建设的应用实际出发,应用数值仿真模拟的方法,对黄土地区客运专线路基工后沉降进行研究探讨。为今后客运专线或高速铁路的设计提供有用的参数或经验。

Numerical Simulation of After-construction Settlement of Deep Loess Roadbed for Railway Passenger Transportation

The passenger transportation has the fast and security characteristics by implementing the separate transportation of passenger and freight, and becomes as more as important mode of passenger transportation in China. In order to guarantee the security and smoothness of the train, and the comfort of passenger according to the design speed operation after opening the passenger transportation, the article puts forward the more strict control standard for the after-construction settlement of railway foundation. Therefore, it is necessary to theoretically and systematically study the after-construction settlement of the roadbed for the passenger transportation. From the application of the passenger transportation engineering construction, the numerical simulation method is applied to study and discuss the after-construction settlement of passenger transportation roadbed in the loess region, which provides the useful parameters and experience for the design of passenger transportation and express railway in the future.
