岩堆形成机理及其路基稳定措施研究

Study of the Formation Mechanism of Rock Heap and the Subgrade Stabilization Measures

岩堆是岩石山坡经过物理、化学作用,形成岩石碎块、岩屑后,通过重力或雨水作用搬运至平缓山坡或山坡坡脚上的疏松堆积物体,属于典型的不良工程地质灾害。文中系统地分析了岩堆的工程地质特征、形态和分类,研究了岩堆的形成机理、破坏模式及稳定性,提出了岩堆路段路基稳定措施。

After the physical and chemical effect, rock2 hillside forms rock fragment and cuttings, and then through the agency of gravity or water, which is transported to the gentle slopes or the slope of hill to form rock heap, a kind of loose accumulation objects. It＇s the typical harmful engineering geology disaster. This paper analyzes the engineering geological characteristics, patterns and classification of rock heap and researches its formation mechanism, failure mode and stability and puts forward measures to keep the stability of rock heap subgrade.
