Abstract

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.
- Multilevel fuzzy synthetic evaluation,
- Blast-fill site,
- Marine soft soil
