摘要
三峡船闸深槽开挖与锚固工程量大 ,工期紧 ,施工强度高 ,施工难度大。因此 ,合理的施工程序有利于边坡稳定和施工 ,是快速和高质量施工的关键。分析了永久船闸直立墙基坑开挖与锚固施工程序的复杂性和进行研究的必要性。介绍了设计阶段研究船闸开挖与锚固的施工程序。对施工过程中研究施工程序时考虑的因素、研究的主要内容以及实际采用的施工程序作了简要的分析、归纳和总结。
The deep chamber trench excavation and chamber wall anchorage of the Three Gorges shiplock are characterized by great quantity, short construction period, high intensity and great difficulty in construction. Therefore a reasonable construction procedure is favourable to the stability of side slopes and to their construction and it is also the key to the rapid and high quality construction. The complexity of the construction procedure for the excavation and anchorage of the permanent shiplock's vertical wall and the research necessity of the construction procedure are analyzed. The research work on excavation and anchorage construction procedure of the shiplock at the design stage is presented. The main factors to be taken into account and the main contents to be studied for the construction procedure research in the construction course as well as the practically adopted construction procedure are briefly analyzed, concluded and summarized.
