| Abstract: | With field cases, the comparison and selection were made on commonly used foundation pit support and water-stop methods; the introduction was made on the double-row piles retaining and high-pressure rotary jet grouting water-stop curtain in saturated sand deep foundation pit. Based on the theoretical calculation and monitoring data, the supporting effect was analyzed, and the application of high-pressure jet grouting water-stop technique was discussed. |
