淮南六方堤水力冲填周期的合理确定

RESONABLE DETERMINATION OF HYDRAULIC SILTING PERIODS OF LIUFANGTI IN HUAINAN

本文根据现场水力冲填试验成果，利用分段泥浆压力法确定出一次冲填最大冲填高度，在此基础上确定出最佳的冲填周期，以便合理预算几十里长六方堤水力冲填加宽加高施工工期及投资。

In this paper, the authors reasonably determine the hydraulic silting periods on the basis of hydraulic test results and making good use of the ″method of sublevel mud pressure″ to calculate the maximum silting height, in order toprovide scientific basis for reasonable budget of the time linit and capital expenditure of the hydraulic silting engineering of tens kilometer long Liufangti.
