| 摘 要： | 本文以山东省淄博-滨州高速公路试验段为例,现场实测了路基的沉降变形,并用有限差分方法计算分析了粉喷桩复合地基的沉降变形.通过比较分析,指出粉喷桩复合地基,能减少加固区的沉降量,但对于下卧层的沉降量影响不大.如果存在较厚的软弱下卧层,沉降量主要来自于下卧层.建议粉喷桩穿过软土层更为可靠.为提高设计质量和施工水平提供理论参考.

| Abstract: | This Paper is based on trial segment of zibo-binzhou highway in Shandong province. The deformation of the basement is surveyed. FLAC-3D procession is used to calculate the settlement of DJMP(Dry Jet Mixing Pile) composite basement. It is pointed, by comparison, that settlement of reinforced zone could be decreased by DJMP composite basement, and the zone under reinforced which could not be influenced. If soft zone bellow composite basement is thicker, the settlement mainly comes from the soft zone. Proposal is given that DJMP should be through out the whole soft zone. The analyzing about the law of settlement provides theory reliance for design and construction. |
