| 中文摘要:压力分散型锚索是一种新型单孔复合锚固体系，其在同一锚索孔中设置多个单元锚索，各单元锚索具有各自不同的自由长度和锚固长度，并通过预先的补偿张拉，使锚索的集中拉力分成为多个较小且荷载数值相等的分散压力分别作用于各单元锚索的锚固段上。结合330国道K17+440～695段路基边坡治理的工程实践,论述了压力分散型预应力锚索的施工工艺以及在施工及工程运行管理中应注意的一些要点。 |

| Abstract:The pressure-dispersing anchor cable is a new type of single-hole composite anchorage system developed in recent years. Several unit cells are set in the same hole, each unit cell with different free length and anchor cable length. By the preliminary compensate tension, the concentration tensile of cable are divided into several small dispersive pressure with equal load value, which respectively acts on cable segment of each unit anchorage. With the engineering practice of slope treatment of K17+440~695 subgrade of 330 national highway, this paper discusses the construction technology of pressure dispersion pre-stressing cable and some key points which should be paid attention in the construction and engineering operation. |
