| 摘 要： | 二期围堰是三峡工程建设的关键，施工技术难度大，施工期短。首先在一般工程地质条件勘察的基础上，针对二期围堰工程建设的特点，对主要的工程地质问题如枯水河床基岩深槽问题、堰基细砂层振动液化与渗透稳定问题、堰基岩土渗透问题等，进行详细的勘察研究，在此基础上提出了二期围堰的设计和施工依据，是二期围堰工程胜利建成的根本保证。 |
| 关 键 词： | 三峡水利工程 二期围堰 工程地质问题 堰基 岩土渗透 河床 围堰 |

| Abstract: | Second-phase cofferdam is key for Three Gorges project,First,on the base of surveying general engineering geology conditions,aim to the characteristics of second-phase cofferdam,main engineering geology problems such as the low water riverbed bed-rock deep-trench,the vibration liquefaction and seepage stability of fine sand layer in cofferdam foundation and the seepage stability of rock and soil in cofferdam foundation,have been surveyed and studied.Then,the design and construction for building second-phase cofferdam.are presented. |
| Keywords: | Three gorges water project second-phase cofferdam the problem of engineering geology |
