经验公式法预测砂岩高速铁路路基沉降

Prediction of the sandstone embankment settlement of the high-speed railway using empirical formula

本文以山东省某城际铁路路基的典型路段为研究对象,预测砂岩路基的沉降.选取影响沉降的主要因素——弹性模量,推导出适用于实际工程的经验公式,弥补了现有理论预测方法的一些不足.

A typical roadbed section of an inter-city high-speed railway was selected in Shandong Province as the research object, and the settlement of sandstone embankment was predicted. Elastic modulus was selected as the main factors to derive a empirical formula to be used in practical engineering, making up for the weakness of the existing theoretical prediction methods.
