地表下沉 meaning in Chinese
ground depression
surface subsidence
Examples
- Study on ground surface subsidence due to underground tunnel excavation
隧道开挖引起地表下沉及其影响分析 - On the basis of the practice on work of extra - insufficient control and the subsidence of vault and the earth ' s surface , cases of engineering surveying techniques applied in the construction supervision in tunnels are discussed
摘要通过超欠挖控制、拱顶下沉、地表下沉的工程实践，讨论在隧道施工监控量测中工程测量技术的应用情况。 - And then according to every process of tunnel construction , simulated analysis is carried out . by combining with monitoring and instrumentation of surround rock periphery displacement and the face of land to sink , surround rock with spray laminating force , surround rock body internal displacement , anchor rod axle force and protect and lining build strength , we have carried out scientific analysis and synthesis judgement of the stability of tunnel wall rock and the security of timbering structure
然后，根据隧道施工的各个工序进行模拟分析，并结合对围岩周边位移、地表下沉、围岩与喷层压力、围岩体内部位移、锚杆轴力、支护及衬砌强度进行的量测与监控，对量测结果作出了科学分析，从而对隧道围岩的稳定性和支护结构的安全性做出了综合评判。 - In order to accurately calculate the mining induced subsidence in thick alluvium areas so as to decrease the mining damage and environment disruption , the calculation of surface subsidence caused by water loss of clay was discussed based on probability integral method and used in a real case
摘要为了更加精确地计算厚冲积层矿区的煤矿开采沉陷问题，减小采动损害与环境破坏，基于煤矿开采沉陷计算的概率积分法，探讨了由于黏土体失水引起的地表沉陷计算问题，推导了黏土体失水引起的地表下沉计算公式，并应用于煤矿实际地表沉陷，加以分析论证。
