隧洞衬砌 meaning in Chinese
tunnel lining
Examples
- Structural analysis for the liner and surrounding rocks of diversion tunnel in jinping waterpower station
锦屏二级水电站深埋引水隧洞衬砌及围岩结构分析 - If the character of wall rock is finer , it is smaller for suffered force and distortion of tunnel pipe liner structure , contrarily it is bigger
性态好的围岩，隧洞衬砌的受力和变形较小，反之则较大。 - In order to calculate the high external water pressure , the rock seepage field and external water pressure coefficient should be treated in detail . concentrated on the questions of high external water pressure and flow of the deep - lying tunnel , the basic theory and method calculating external water pressure are systematically studied , the high external water pressure of jinping cascade 2 hydropower station is analyzed and studied in detail
本文在总结前人研究成果的基础上，围绕深埋隧洞的突涌水和高外水压力问题，系统地研究了深埋隧洞衬砌水荷载和外水压力的作用机理及计算方法等理论，并对锦屏二级水电站深埋引水隧洞的外水压力问题进行了详细的分析和研究。 - Complicated hydrologic and geographic conditions , and the large scale of the xiaolangdi hydraulic project on the yellow river are introduced briefly . three desilting tunnels are designed to meet the requirements of flood control , sediment discharge and runoff regulation . according to the performance requirements of desilting tunnels , the tunnel lining down - stream of the grouting curtain is designed to be post - tensional prestressed lining . on the basis of investigation and research , experiements and analysis , the unbonded prestressing system is used . it is the largest unbonded prestressed tunnel lining project in the world , and the first one in china
简介黄河小浪底水利枢纽复杂的水文、地质条件以及庞大的工程规模.该枢纽设计有3条排沙洞，担负着泄洪、排沙、调节径流和保证进水口不被泥沙淤堵的任务.根据排沙洞的水库运用要求，灌浆帷幕下游排沙洞洞身段设计为混凝土后张预应力隧洞.通过大量的调研、试验、分析论证，在施工前确定该预应力方案选用无粘结预应力系统，成为目前世界上规模最大的无粘结预应力隧洞衬砌工程，在国内尚属首例
