摘要
介绍了用预应力锚索锚固于既有线路基,对因施工产生的自身临空面进行加固的工程实例,探讨了土压力计算和锚拉式槽钢“井”字梁加固高陡边坡挡墙的原理、工艺及方法,对防护工程空间有限的工程和运行中交通要道的改造或者抢险,具有特别现实的意义。
The application of prestressed anchoring cable in roadbed treatment of existing line is introduced.Free faced caused by construction is reinforced.Combined with practical work calculation of earth pressure and the principle of the method combined with anchored caission beam and retaining wall as well as technology and method are introduced,which has practical significance for the work with limited protection space and reconstruction work of heavy traffic road.
