| 摘 要： | 利用多种桩联合加固软弱地基的方法是一种地基处理的新技术。对已采用CFG桩处理过的复合地基进行分析,再次采用高压旋喷桩进行地基加固,极大提高了地基承载力,减小了地基的压缩性,并在开封东京银座工程中取得了成功应用。提出的地基处理方法适合于在软弱地基上建造高层建筑物采用。

| Abstract: | Multi-element composite ground is a new technology for foundation treatment. The composite ground treated by CFG pile has been consolidated again by jet grouting pile. The bearing capacity has improved and compressibility has decreased observably. This technique has been applied to ＂Dongjing Silvern Building＂ engineering successfully. The technique can be applied to foundation treatment for high-layer-building constructed. |
