自适应锚索在地铁车站施工中的应用研究

RESEARCH ON APPLICATION OF ADAPTIVE ANCHORAGE CABLE IN CONSTRUCTIONS OF METRO STATION

介绍自适应锚索的构造及特点,结合地铁虾子蝙车站工程进行自适应锚索的设计与施工研究。对比评价表明,自适应锚索具有锚索数量少、造价低及工期短等优点。可根据计算锚索极限承载力来设计加工相应的承载体,以满足不同地层的加固需求。

In order to study the application of adaptive anchorage cable in practical project, the structure and characteristics of the adaptive anchorage cable are introduced firstly, then research on design and construction of the adaptive anchorage cable based on the project of Xiazibian metro station. According to the comparison and evaluation of engineering, it reveals that the adaptive anchorage cable has the advantages such as less quantity of anchor cables, lower cost and shorter duration of working, compare with traditional anchorage cables. Moreover, in the light of the calculation of the ultimate bearing capacity of the anchorage cable, the corresponding load-bearing bodies at all levels of adaptive anchorage cable can be designed and fabricated, to meet the strengthening needs of different strata.
