发布时间：2019-02-19 20:40
【摘要】：随着城市地铁盾构隧道的日益兴建,球状风化体作为影响盾构顺利掘进的重难点愈发凸显,盾构区间球状风化体的预处理技术已成为国内外研究的热点。综述已有文献,在对球状风化体形成机理、原因及处理必要性分析的基础上,根据其形状、大小、所处地理位置,结合周边环境的实际情况,且综合考虑技术、成本、工期、安全等因素,将盾构区间球状风化体预处理分为:直接掘进通过、地表预处理、洞内处理三大类,并详细论述了九种处理方法的适用范围、优缺点。最后,提出现场处理的合理化建议,为盾构区间风化体的预处理技术提供指导。
[Abstract]:With the increasing construction of shield tunnel in urban subway, the spherical weathered body is becoming more and more difficult to influence the smooth tunneling of shield tunneling. The pretreatment technology of spherical weathered body in shield section has become a hot research topic at home and abroad. Based on the analysis of the formation mechanism, causes and treatment necessity of the spherical weathered body, according to its shape, size, geographical position and the actual situation of the surrounding environment, and considering the technology, the cost, the time limit, the paper summarizes the existing literature. The pretreatment of spherical weathered body in shield section is divided into three categories: direct tunneling, surface pretreatment and hole treatment. The application scope, advantages and disadvantages of nine treatment methods are discussed in detail. Finally, some reasonable suggestions are put forward to provide guidance for the pretreatment of weathered body in shield section.
