摘要

摘要: 面板堆石坝是一种常见的挡水构筑物。在堆石填筑技术的基础上,通过堆石体中布设预应力锚索和下游坝坡增设钢筋混凝土框架网,将锚索分别与上游坝坡面板和下游坝坡框架锚固起来,提出了一种堆石体与锚固体协同工作、增强稳定性、减少填筑体的新型坝体结构——锚固面板堆石坝。阐述了锚固面板堆石坝的构筑方法,应用邓肯—张E-B 模型的有限元数值方法,比较分析了堆石坝有、无预应力锚索加固条件下的变形特征及稳定性。分析表明锚固面板可以提高坝体的稳定性、缩短坝体底宽、减少填筑工程量,获得了经济效益。

Abstract: The concrete face rockfill dam is a kind of common water retaining structures. A new structural pattern of rockfill dam, named as anchoring face rockfill dam, is proposed by the prestress cable anchoring the upstream concrete face and downstream concrete framwork. The prestress anchorage cable in the rockfill dam could works together with rockfill and concrete face and framework to keep the stability. The construction method for the anchoring face rockfill dam is expressed. The deformation characteristics and stability of anchoring face rockfill dam are analyzed by the numerical method with Duncan-Chang E-B model. The deformation characteristics and stability of the rockfill dam with and without prestressed anchorage cable are compared and analyzed. According to the deformation characteristics during construction and storage period analyzing results, the anchoring face rockfill dam can increase the dam slope rate. The stability of dam slope is analyzed by using the strength reduction method. It is shown that the width of the bottom of dam for the anchoring face rockfill dam can reduce, and the filling quantity decrease to obtain the economic benefit.
