锚杆抗滑桩体系的群桩、群锚效应研究现状分析

对锚杆抗滑桩系统的群桩效应、群锚效应的研究现状进行了分析。虽然锚杆抗滑桩体系和预应力锚索抗滑桩体系近年来在工程中大量应用,但其设计计算理论研究远远滞后于工程应用。将桩-锚作为一个系统来研究抗滑桩的群桩效应和锚杆或预应力锚索群锚效应的论文至今很少见到,国外对于群桩效应的研究主要集中在圆形截面桩上,对于矩形截面桩的研究成果则不多见。对于群锚效应问题,也存在理论远远落后于工程实践的情况,为了避免群锚效应的发生,只能给出一些建议性的措施,因此,加强对锚索抗滑桩系统的群桩效应、群锚效应的研究,不仅是十分必要的,也具有重要的理论意义和应用价值。

Analysis on Researche Reality of the Effects of Pile Groups and Anchor Groups in Anchor Anti-slide Piles

In the paper,the author analyzes the research situation of effects of pile groups and anchor groups in the anchor anti-slide pile system.There are considerable applications of the anchor anti-slide pile system and prestressed anchor anti-slide system in the projects recently,however,its design and calculating theory research far lags behind its application in the projects.Nothing to say the papers on research of group pile effects and group anchor effects of anti-slide piles as whole unit of pile-anchor,when it comes to the overseas counterparts,they mainly focus on the cyclical section pile,and few on the rectangle section pile.This is also the case when it comes to the effects on group anchor.Thus,in order to avoid occurring of effects on the group anchors,suggestive measures have been put forward.From this point of view,it is quite crucial to pay great attention to the study of effects on group piles and group anchors in the anchor anti-slide pile system,which is theoretically important and has great application value.
