淮河及大堤的优质煤层，经过多年开采，使堤身累计下沉５～９ｍ。本文介绍综合采用静动力有限元分析、离心模型试验、振动台试验、电模拟试验、现场调查及现场试验等方法对受采动影响的淮堤进行安全分析论证，得出淮堤基本安全的结论；并采取了复合土工膜防渗、振冲加固堤基等措施。经多年运行证明，结论是可信的，措施是有效的。 Huaihe and the dike of high-quality coal seam, after years of mining, so that the bank sink 5 ~ 9m in total. This paper presents the conclusion that the safety of the Huai River embankment is concluded by comprehensively using the methods of static and dynamic finite element analysis, centrifugal model test, shaking table test, electric simulation test, field investigation and field test to carry out the safety analysis and demonstration of the affected embankment. ; And taken a composite geomembrane seepage, vibration reinforcement embankment and other measures. After years of operation proved that the conclusion is credible, the measure is effective.
