摘要
为了对存在安全风险与渗水问题的习水县塘房水库进行加固除险,在分析该水库基础数据、水位及地质数据的基础上,设计一系列除险加固方案。计算和试件测试结果显示,加固后的坝坡最小安全系数大于规范设定的1.15阈值;坝体、侧墙、坝顶、放水建筑物、上游坝坡、排水盲沟试块28天龄期抗压强度均高于对应设计值;计算出的实际坡降为0.34,小于0.90的临界坡降,表明此次设计的除险加固方案能达到预期效果。
In order to reinforce and eliminate safety risks and water seepage issues in the Tangfang reservoir in Xishui county,this study analyzed the basic data,water level,and geological data of the reservoir,and designed a series of reinforcement plans.The calculation and specimen testing results show that the minimum safety factor of the reinforced dam slope is greater than the 1.15 threshold set by the specification.The compressive strength of the dam body,side walls,dam crest,drainage structures,upstream dam slopes,and drainage blind ditch test blocks at the age of 28 days are all higher than the corresponding design values.The calculated actual slope is 0.34,which is less than the critical slope of 0.90.It can be seen that the reinforcement plan designed in this design can achieve the expected effect.
