摘　　要：设计一种新型具有密封和排气功能的止浆塞,采用有限元方法对止浆塞的实际工作状态进行数值模拟分析,对外塞胶料进行优化。结果表明:随着止浆塞外塞胶料的硬度的减小,止浆塞的密封性能提高;综合考虑密封性能和成本,确定止浆塞外塞采用邵尔A型硬度为40度的天然橡胶胶料。A new type of stop-grouting plug with sealing and exhausting functions was designed,and numerical simulation analysis of the actual working state of the stop-grouting plug was carried out using the finite element method to optimize the compound of the outer part of the stop-grouting plug.The results showed that as the hardness of the compound for the outer part of the stop-grouting plug decreased,the sealing performance of the stop-grouting plug was improved.Taking into account both sealing performance and cost,it was determined that the outer part of the stop-grouting plug was made of NR compound with a Shore A hardness of 40 degrees.
