摘　　要：结合某高速公路试验路段路基填筑,通过对其含水量的变化进行动态监测以及相应的抗剪切强度试验,建立了路基安全性分析模型;在此基础上,对试验路段的路基在不同含水量条件下的安全系数进行计算分析,得出含水量变化对路基安全性影响的规律。Combined with the subgrade filling of certain highway section for test, the model for analysis is established through dynamic monitoring on the change of the subgrade＇s moisture subgrade safety content and the corresponded shear strength test. Based on this, the safety factor could be calculated and analyzed under different moisture contents of the subgrade herein and the laws of the change of moisture content affecting subgrade safety could be obtained.
