摘要
针对深江铁路珠江口隧道工程盾构工作井建设时间紧、任务重的要求,根据工作井的结构特点综合比较了采用顺作法、逆作法和半逆作法施工的优缺点与可行性,最终采用半逆作法施工方案。结果表明,采用半逆作法能有效保障施工工期和施工质量。
Aiming at the requirement of tight construction time and heavy task,the advantages and disadvantages and feasibility of using forward method,reverse method and semi-reverse method are compared according to the structural characteristics of the working well,and the semi-reverse method is finally adopted.The results show that the semi-reverse method can effectively guarantee the construction period and construction quality.
