公路沥青混凝土路面调坡工程的质量控制

公路包括高速公路、一级公路等公路路面由于路基沉陷经过一段时间运行后,路面会出现不均匀沉降,使原设计的公路竖曲线线型被改变,严重的更会引起公路的行车安全。针对这种情况,公路管理部门通常的做法是测定公路沉降后的路面标高,再以这些观测成果按公路等级重新铺筑面层,以调整或改善其路线线型,使其满足公路等级的通行要求。

Stability evaluation and protection of slope for Laosongling-Yanji Highway

The authors analyzed the engineering geological characteristics of the slope of the study area (K75+840-K76+340). Two typical cross-sections have been chosen to analyze the failure modes after the excavation of the highway. Different types of the failure modes have been calculated and analyzed. The results show that some dealing methods have been advised to ensure the stability of the slopes.
