摘要
淮河出山店水库在蓄水到90m时,将会形成河岸型和半岛型两种库岸。以平昌关地块(河岸型)和龙井地块(半岛型)为研究对象,运用GMS分别进行渗流模拟完成浸没预测。对比预测结果,平昌关地块的浸没长度较长,且浸没长度-坡降曲线较缓;统计浸没长度-坡降数据,拟合出浸没长度-坡降幂函数曲线。对比分析两个地块浸没结果差异产生的因素,并建立计算模型验证得到库岸的坡度是影响浸没长度的主要几何因素。
When the water level of Chushandian reservoir gets to 90 meters,there will form the two kinds of shores such as the river bank type and the peninsula type.Taking Pingchangguan block（river bank type） and Longjing block（peninsula type） as the study subjects,the seepage simulation and the immersion prediction are accomplished by using GMS.The forecast results show that the immersion length in the Pingchangguan block is longer than that in the Longjing block,and the curve for the immersion length and the grade is quite gentler.The data for the immersion length and the grade are counted,and the exponential curve for the immersion length and the grade is fitted.Comparing the factors which cause the difference immersion results in the two blocks,the computational model is developed.It is verified that the grade of the bank is the main geometrical factor which affects the immersion length.
