摘要
三峡工程大江截流，流量大、水深、抛填强度高。二期土石围堰的防渗墙要穿越河床块球体并嵌入弱风化岩层，工程难度大、施工强度高，其难度和强度均超过国内外同类工程。监理机构加强对合同目标的控制，对施工全过程实行跟踪监理和旁站监督，在监理过程中，贯彻以“安全生产为基础，施工质量为中心，合同工期为重点，投资效益为目标”的２８字方针，促进了施工进展，为大江截流和基坑按期抽水做出了贡献。
TGP main river channel closure has such features as large discharge, deep water and high dumping intensity. The seepage control walls of the second stage cofferdam need to penetrate through the boulder zone and into weakly weathered layer, with difficult field operation and very high construction intensity, both of them surpass the levels of similar projects at home and abroad. The supervision unit strengthened the control of contract goals, and carried out the tracing and by job site supervision in the whole process of construction. The guideline of “taking the safe operation as base, the engineering quality as center, the contract schedule as emphasis, and the investment effect as goal” was implemented in the process of supervision, promoting the progress of construction, and contributing to the main river channel closure and the dewatering of the foundation pit on time.
