我国过去修建的鉄路,包括解放后初期修建的宝成、鷹厦等綫,一般选綫多单純着重自然地势难易和节約投資,对地质情况則考虑很少或不够周密。例如地质情况沒有弄清,就定了綫,路塹边坡采用的过陡,綫路穿越堆积层或滑动地带等多是,排水和防护工程能减就减,以致有些线路在修建期間就不断发生坍方,通車以后,每逢雨季,就出現滑坡或坍塌,如宝成綫这种情况一直持續了奸几年。有些病害如能在設計和施工阶段,摸清底細,从設計和施工上予以合理处理,是会使病害减少的。茲就宝成綫所遇到的坍方滑坡問題以及拟定的处理方法介紹如下。一、由地面或地下水渗入造成的病害的处理方法 In the past, the Kushiro Road in our country was built, including the Baocheng and Yinghaxia lines built in the early post-liberation period. The general route selection simply focused on the natural topography and saving investment, and little or no consideration for the geological conditions. For example, the geological conditions have not been ascertained to determine the line, the cutting slope used too steep, the line crossing the accumulation layer or sliding zone and so on, drainage and protection works can be reduced, so that some lines in the continuous collapse during construction After the traffic opened, whenever the rainy season, landslides or collapsed, such as Po-line this situation has continued for several years. Some diseases, such as design and construction phase, find out clearly, from the design and construction to be properly handled, it will reduce the disease. The landslide problem encountered by Po-cheng Line and the proposed treatment method are described below. First, by the ground or groundwater infiltration caused by the treatment of diseases
