［摘要］提供了一種通過RJP工法封底加固替代抽降承壓水的新思路及工藝方法。該方法通過RJP滿堂加固與工程樁緊密咬合形成整體以解決承壓水抗突涌穩(wěn)定問題，可以減少止水帷幕的插入深度，并避免抽降承壓水對環(huán)境設施的擾動。該方法在鄰近地鐵設施的深基坑工程中取得了良好的實踐效果。

Abstract: This paper presents a new method of using RJP-reinforcement instead of confined water dewatering. The method utilizes RJP-reinforcement and structure piles to resist the inrushing of confined water. With this method, the length of curtain for cutting off water can be reduced, and the environment influence of confined water dewatering can be avoided. The method was applied in a deep exaction nearing metro utilities successfully.
Keywords: RJP; deep excavation; confined water dewatering
