Study of failure mechanism of retaining wall with pile amp; amp; anchor structure in the three - gorges reservoir region 三峡库区某桩锚挡墙失稳机理分析
Probe into earth pressure calculation and structure optimization of pile - anchor support for deep foundation pit 深基坑桩锚支护土压力计算及结构优化探讨
What we have done here provides developing calculation model for the force - deformation calculation and process control of pars during construction 为桩锚支护结构施工进程中受力变形的设计计算和过程控制提供了动态计算模型。
( 6 ) the thesis puts forward the pile - top displacement control method , and it can account the least force of the anchor wire on anti - slide pile ( 6 )本文提出了锚拉抗滑桩锚拉力计算的桩顶位移控制法，计算控制桩顶位移所需的最小锚拉力。
Secondly , compared with specification jgj 120 - 99 , the problem of method which be using was pointed out base on a great number of numerical simulation , the interaction between pile - anchor supporting and soil nailing was analyzed 其次,针对现行桩锚复合土钉支护设计方法,在大量数值模拟的基础上,通过与规程进行对比,指出现行方法中存在的一些问题,并分析了土钉支护与桩锚支护二者之间的相互作用。
Based on observing several engineering practices , an assumption is put forward that there are unloading arches in the soil between the piles . in order to research the effect of soil arch , the author designs an indoor model and analyzes the result of the exam 本文通过几个工程实践所表现出来的与传统认识相悖的现象，指出了传统认识在实践面前站不住脚，给出桩锚体系立柱间土体存在卸荷拱的假定。
Abstract : taking the earth retaining engineering in nan guang road , yibin city as an example , the authors discuss the design method and construction essential in the treatment of earth filled slope using pile - archor retaining wall to stablize the slope and make full use of land 文摘:以宜宾市南广路挡土墙工程为例，介绍了填方边坡处理时用桩锚挡土墙进行支挡，以便充分利用土地的设计思路和施工要点。
In this paper , author compare with shenzhen holiday plaza project ( be known as firstly deepest foundation pit , deepest excavation depth is 21m ) , use combinative method for theory guidance , test study , simulation analysis , project application and information feedback , entirely and deeply study prestress anchor cable composite soil nail , and also make a pilot study for deformation of pile anchor composite soil nail 本文以深圳假日广场深基坑支护工程(号称“深圳第一坑” ,最深开挖21m )为背景,采用了理论指导、试验研究、模拟分析、工程应用和信息反馈相结合的方法,对预应力锚索复合土钉支护结构进行了全面深入的研究,对桩锚式复合土钉支护结构的变形进行了初步研究。
The emphasis is given on the studying of the horizontal displacement on the retaining structure consist of piles and anchors , which is a frequent type of retaining structure . it is founded that the rigidity of anchors and magnitude of pre - stress are the main factors which influence the deformation of retaining structures . the optimal design method on pile - anchor systems is presented 桩锚支护是一种常见的基坑支护模式，本文以桩锚支护结构水平位移为重点，对支护结构刚度、支撑刚度与预应力、支护桩入土深度等对桩顶水平位移的影响进行了分析，指出在桩锚支护体系中，锚杆支撑刚度及预应力对基坑变形的影响最为明显，并通过工程实例加以验证。
