龙滩水电站右岸航道边坡预应力锚索施工

龙滩水电站航道边坡采用粘结式和无粘结式端锚型锚索进行深层支护，因设计布置的锚索数量多、锚索方位角和倾角相互交错、边坡地质条件复杂、施工工期紧等因素，给施工带来许多困难。为此，在施工中通过对锚索工作原理进行分析，确定锚索施工需重点控制的工序和控制措施，使得工程按期、优质完成。

Prestress Anchor Construction at the Right Bank Slope of Longtan Hydropower Station

Bonded anchor and un-bonded anchor cables were utilized in the side-slope' s deep support of ship channel in Longtan hydropower station. There are a lot of difficulties in the construction because of a large number of anchor cables in the design arrangement, mutually interlocking azimuth angle and inclination angle, complex geologic conditions of sites, limited construction period etc. Therefore, based on analyzing the work mechanism of anchor cables, the key control processes and countermeasures were determined in the anchor cables construction, which ensure this side-slope project to be finished on time, and with a high quality.
