| 摘 要： | 在地质勘探成果的基础上,评价了芭茅河水库大坝原设计施工的渗流控制措施,根据运行过程中出现的渗流问题和渗流有限元计算分析,对大坝的渗流安全进行了评价.在设计洪水位和校核洪水位下,河床砾质粗砂的水平坡降超过了其允许出逸坡降,可能产生管涌破坏,大坝渗流性态不安全,并提出了相应的加固处理措施.

| Abstract: | Based on geological exploration results of Bamaohe Reservoir Dam,the seepage controlling measures in the old design and construction are evaluated firstly.According to the seepage problems in operation and seepage finite element calculation and analysis,the seepage safety of the dam is evaluated.At the design and check flood level,the horizontal gradient of gravelly coarse sand on the riverbed is larger then its allowable gradient;and it may bring piping seepage failure.It is concluded that the seepage state is unsafe.Then the measures to reinforce the dam are put forward. |
