| 摘 要： | 选择软土的成因类型、工程性质、空间分布及场地工程环境4个二级评价影响因素和相对应的16个一级单因素评价指标,采用模糊数学的方法,建立了天津滨海新区软土工程地质分区多级模糊综合评判模型。利用该模型对一般道路、货场、单层厂房等轻型建筑地基作用的浅部层进行分区,结果表明该区软土工程场地条件由西向东逐渐变差,特别是吹填场地为该区最不利的工程场地。

| Abstract: | This paper chooses the genetic type, engineering properties, space distribution, and engineering site environment of soft soil as the second level evaluation factors and their corresponding 16 individual factors as the first level evaluation factors. It then uses the method of fuzzy mathematics to build a multilevel fuzzy synthetic evaluation model especially applicable to the engineering geology of the soft soil in Tianjin Binhai New Area. This model is used to zone the shallow layer affected by light building foundations of ordinary road, yard, and single storey workshop. The results show that the soft soil engineering conditions gradually become poorer from west to east. Particularly the blast-fill site is the most unfavorable engineering site in the area. |
