高速公路边坡工程工后稳定性评估

如何对已建成、运营通车的高速公路的边坡进行全面工后评估,掌握边坡的稳定情况、变形趋势,并为边坡养护提供科学的依据成为业界日益关注的课题。根据运营期高速公路边坡工程特点,基于边坡工程工后评估实践经验,提出了边坡工后稳定性评估的方法,主要包括路堑边坡工程分类、路堑边坡工程病害分类、稳定性评估和病害工程整治对策等4个方面的内容;通过工程实例,表明所提出的边坡工后稳定性评估方法是可行的。

Assessment on Post-construction Stability of Highway Slope Engineering

How to make comprehensive post-construction evaluation on the slope of highway which has been built and opened to traffic, how to know the slope＇stability and its deformation trend, and how to offer scientific basis for slope maintenance, are the issues to be paid more and more attention in the industry. According to the features of slope engineering for highway in operation and the practical experience on the post- construction evaluation for such works, the main contents of the evaluation were put forward, including classification of cutting slope and the diseases therein, stability assessment and countermeasures for the disease control. Through practical project cases, it was showed that the post-construction slope stability assessment proposed herein was feasible.
