粘土固化注浆帷幕对重金属离子的吸附特性 - Its dam foundation grout curtain and backfilling technologies are advanced
在大坝基础工程帷幕灌浆、回填技术上处同行之首。 - 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 - According to the geological conditions of baise project , erosive bands and joint fissures , f6 fault and grout curtain are fully simulated to establish 3d numerical model of the dam and its foundation . 3d non - linear fem is used to analyze the stress and strain and to appraise the operation state of both the dam and it ' s foundation under different operation conditions . by overloading the upstream water level and reducing rock strength parameter , the dam foundation ' s degradation process is simulated and the damage pattern and paths are determined , and finally the safety factor is determined
2 、根据百色的地形地质条件，充分模拟了蚀变带、节理裂隙、 f6断层、灌浆帷幕等，较为真实地建立了坝体与地基相互作用的整体三维数值模型；采用有限元法对坝体及坝基在不同工况下的应力应变状态开展分析，评价各工况下坝基的运行状态；而后采用超载法和综合法对大坝稳定性进行分析，模拟坝基的渐进性破坏过程，从而得到坝基在超载和强度下降过程中的破坏模式和破坏发展路径，最终确定坝基超载安全系数和综合安全系数。
