摘要
针对软土富水地区地铁盾构始发端不具备土体加固条件或难以保证土体加固效果的情况,介绍了钢套筒辅助始发工艺。工程实践表明,该工艺可较好地应用于盾构始发加固长度不足的工程中。
In view of the situation that the starting end of subway shield in water-rich soft soil area dose not have reinforcement conditions or it is difficult to ensure soil effect,the paper introduced the technology of shield launching assisted by steel sleeve.Engineering practice shows that this technologycan be well applied to the project with insufficient reinforcement length of shield.
