煤矿沉陷区铁路路基加固

The railway roadbed reinforcement in coal mining subsidence area

结合某煤矿沉陷区铁路专用线工程的实际情况,验算了该路基的地基承载力,提出了土工格栅加固方案,并对加固后的路堤稳定性进行了分析,结果表明,加固后的路堤滑动安全系数满足规范要求,可正常使用。

Combining with the actual situation of a certain coal mining subsidence area railway specific engineering,this paper calculated the foundation bearing capacity of roadbed,proposed the geo-grid reinforcement scheme,and analyzes the embankment stability after reinforcement,the results showed that the embankment sliding safety coefficient after reinforcement meet the specification requirements,could be normal use.
