摘要
木里煤田特殊的冻融环境使露天煤炭开采遇到了多种冻土问题,保证冻岩土边坡安全运行既是生产迫切需要也是解决冻岩土工程问题的目标。通过对该区域冻岩土体特征分析,依据监测技术有针对性的制定边坡监测方案。初步监测成果认为,木里地区冻岩土温度、位移及水位变化存有空间差异性,其物理响应具有一定季节效应,也验证了本监测方案的合理性。
Special freeze-thawing environment in Mull coalfield makes open-pit coal mining meet a variety of frozen soil problems. To ensure the safe operation of frozen rock and soil slope is not only the urgent need of production, but also the goal of solving frozen rock and soil engineering problems. Through analyzing characteristics of frozen rock and soil in the region, the article makes slope monitoring program according to monitoring technology. Preliminary monitoring results show that frozen rock and soil temperature, displacement and water level changes in Mull area have spatial difference, which physical response has a certain seasonal effect and also verifies rationality of the monitoring plan.
