浅析路基检测方法的探讨

Analysis of Subgrade Test Methods

铁路路基在建过程中及铺轨前,为保证路基整体压实质量满足设计要求,需对路基进行检测及路基评估。文章通过介绍了路基质量检测方法如地基系数、灌砂法、动态变形模量、动力触探法和探地雷达法等的测量原理及实际工程应用中存在的优缺点,为铁路路基质量检测和施工控制提供参考。

In order to guarantee the quality of subgrade compaction up to the design requirement, the subgrade should be tested and evaluated during the construction of railway suhgrade and prior to track laying. The thesis expatiates on the test methods of roadbed quality such as suhgrade coefficient, Idling sand method, dynamie strain modulus, dynamometry and ground penetrating radar method and also expounds the virtues and defects in the application so as to provide reference for the quality inspection and construction control of the railway subgrade.
