1、毕业设计（论文）混凝土重力坝设计计算书摘要陵江水利枢纽工程是位于陵江上的Ⅰ级建筑物由厂房段坝段溢流坝段大孔口溢流坝段深孔溢流坝和坝后厂房等组成装机容量90万千瓦6×15万千瓦它是一项具有防洪发电灌溉航运和养殖等综合效益的改革大自然的伟大工程本次的设计的内容包括施工导流和基础处理设计在设计中我们充分在地分析论证了枢纽处的地形地貌条件水文地质情况气象资料等结合当地的施工条件依据各类水利工程规范初步拟定导流方式采用分段围堰法导流其导流时段为全年导流根据基本资料选定了导流标准为20年一遇洪水标准通过定量计算进行了导流方案的经济比较选择导流方案为土石围堰束窄的河床和导

2、流底孔泄流在导流建筑物的设计中导流底孔采用矩形在导流建筑物的施工中通过各建筑物工程量的计算确定了各类施工机械的类型及台数在截流设计中通过截流水力计算确定了在不同流速情况下各截流材料的粒径大小及其数量在基坑排水设计中通过各期排水量的计算确定了各期的排水设备在基础处理部分运用钻孔爆破的方法开挖坝基设计具体的爆破参数及其起爆网络为提高坝基整体性增强基岩承载力并增加基岩密实性减少通过基础表层岩石渗漏量还需对坝基进行固结灌浆和帷幕灌浆为此设计灌浆的布置方式和基本参数关键词水利枢纽施工导流基础处理AbstractTheLingjiangHydro-junctionPro
