| 摘 要： | 通过对嘉兴市浅部主要地基土体的构成及物理力学指标相关性的研究,得到了符合本区地基土特点的物理力学性质指标与原位试验数据间的回归方程。利用大量勘察资料,分析了④2层粉性土的工程特性、分布状况及用作桩基持力层可行性,分析结果表明,当厚度大于3.5 m且较均匀、静力触探锥尖阻力在4.0 MPa以上时,可以作为桩基持力层。 |

| Abstract: | This study was conducted to investigate composition of major shallow foundation soil mass and the indicators of physical mechanics in Jiaxing City to obtain the regression equation conforming with in sity test of physical mechanics indicators of featrues of local foundation soil mass.Based on massive quantities of exploration materials,this study was to analyze engineering features,distribution status,and the feasibility of silty clay to be used as the bearing layer of the pile in Layer ④2.The analytical results showed that when the silty clay with the uniform depth was over 3.5 m and the cone tip resistance in static sounding of over 4.0 MPa,it could be used as bearing layer of the pile. |
