风化花岗岩路基土动态力学性能的试验研究

Trial Study on Dynamic Behaviors of Weathered Granite Subgrade Soil

风化花岗岩一般物理力学性质的研究已积累了较丰富的资料 ,而动态力学特性方面的研究却相对薄弱 ,本文根据车辆荷载作用下路基动态受力的特点 ,对风化花岗岩路基土的加卸载回弹模量、动变形、动强度进行了试验研究 。

Many data are accumulated on the physics mechanical properties of weathered granite, but the data of its dynamic behaviors are poor. According to the dynamic subgrade characteristic subjected to the vehicle loading, the tests of modulus of resilience under repeated loading, dynamic strength and dynamic strain are studied in laboratory for expecting to gain the dynamic behaviors of weathered granite soil.
