摘要
新疆乌斯通沟水库坝址区年内温差和昼夜温差均很大,冬季寒冷,夏季酷热,存在两岸山体地形起伏较大、地质条件复杂、深厚覆盖层、施工时段受气候影响大等问题,坝型选择制约因素较多。本文从地形地质条件、基础开挖及防渗、建筑材料、坝体抗震性能、施工条件、工程安全维修条件和工程投资等方面,对沥青混凝土心墙砂砾石坝和钢筋混凝土面板砂砾石坝进行综合技术经济比较。结果表明,沥青混凝土心墙砂砾石坝防渗工程量小,防渗、抗震性能好,与两岸坝肩搭接容易,心墙在坝体内抗老化性能好,施工时段受气候影响较小。因此,乌斯通沟水库选择沥青混凝土心墙砂砾石坝作为建设坝型。
In the dam site of Wushenggou Reservoir in Xinjiang,the temperature difference between the year and night is very large,cold in winter and hot in summer,and there are many problems such as large mountain topography fluctuation on both sides,complex geological conditions,deep overburden layer,and great influence of climate during construction period.There are many restricting factors in the selection of dam type.In this paper,from the aspects of topographic and geological conditions,foundation excavation and anti-seepage,building materials,dam body seismic performance,construction conditions,engineering safety maintenance conditions and engineering investment,etc.,the asphalt concrete core sand-gravel dam and concrete face sand-gravel dam are comprehensively analyzed.techno-economic comparison.The results show that the asphalt concrete core sand-gravel dam has a small amount of anti-seepage engineering,good anti-seepage and anti-seismic performance,easy overlap with the dam abutments on both banks,and good anti-aging performance of the core wall in the dam body,the construction period is less affected by climate.Therefore,the asphalt concrete core sand-gravel dam was chosen as the construction dam type for Wustonggou Reservoir.
