摘要:

针对盾构施工地质复杂、易出现突变载荷而造成掘进装备失效的问题,提出盾构推进系统顺应性的概念并定义其评价指标.以调速阀模式为例建立盾构推进系统解析模型,计算顺应性评价指标,研究蓄能器、溢流元件、油液特性、长管道效应等对顺应特性的影响.采用MATLAB/GUI工具开发顺应性软件设计平台,以国内某地铁工程中遇到的工程载荷为条件设计基于顺应性的新型盾构推进系统,分析比较国外某典型盾构推进系统和新型盾构推进系统的顺应曲线.结果表明,新型盾构推进系统顺应性较现有盾构推进系统提高25%.

Abstract:

 Considering the geological complex and problems of equipment failure caused by sudden change excavating load, the concept of compliance was proposed and its evaluation index for a thrust system of shield tunnel boring machine was defined. The effect of accumulator, overflow valve, oil properties, long pipe, etc. on the compliance characteristics of the system was analyzed.An analytical model of shield thrust system was established and its compliance evaluation index was calculated taking a flow control valve mode system as an example.A design software platform with MATLAB/GUI was developed based on the evaluation index.A new shield thrust system was designed according to engineering loads in a certain domestic tunneling project. Then the compliance index curves of a typical foreign shield thrust system and the new developed one were compared. Results showed that the compliance index of the new shield thrust system increased by 25% than that of existing one.
