摘要
青兰高速公路二期路基病害严重段共有4段。主要病害是土石混填路基段开裂严重,局部沉陷。其原因是排水构造物接缝处渗水,造成路基含水量过大,以及湿陷性黄土和施工材料、施工工艺等造成路基不均匀沉降。通过现场挖验、踏勘,针对各段的病害情况,提出不同的治理措施,实践证明,治理效果良好。
There are 4 sections of Qingdao-Lanzhou Highway Phase II subject to serious subgrade diseases which mainly contain serious cracking and local settlement in the section of rock-soil mixture subgrade. The uneven settlement of the subgrade arises out of excess water content in the subgrade which is resulted from water seepage at the joint of drainage structure, collapsible loess and construction materials, construction process and so on. Through field investigation and in connection with the diseases in every sections, different prevention measures are proposed. The practice proves that the treatment effect is good.
