膨胀土路基边坡设计与施工是公路路基设计与施工难点之一。文章依据膨胀土的基本物理、力学特性,以及边坡变形、破坏形式,针对目前我国公路膨胀土路基边坡设计和施工的实践情况,及存在的主要问题,提出公路膨胀土路堑边坡设计与施工的具体原则,以及设计支护方案和措施及配套的施工技术要求,减少设计失误,避免施工病害,并指出今后仍需加强研究的方向。
The design and construction of expansive soil roadbed slope is one of the difficulties in the design and construction of highway subgrade. Based on the basic physical and mechanical properties of expansive soils, and the deformation and failure modes of the slope, aiming at the current situation of the design and construction of the highway expansive soils in our country and the main problems, The specific principles of construction, the design of support programs and measures and the supporting construction technology requirements, the reduction of design errors and the avoidance of construction diseases, and pointed out the need of further strengthening the research direction in the future.
