摘　　要：该论文根据江苏某高速公路软土地基工程地质问题的出现 ,就该地区的水文工程地质条件、软土分布规律、分布特点、典型路段软土的力学强度指标进行了深入的分析、探讨 ,总结了我国沿海地区高速公路软土地基出现的地质灾害多是因为软土层纵横断面厚薄分布不均、勘测过程中现场及室内试验提供的设计指标与实际差异过大等综合因素造成。经综合对比我国沿海地区高速公路软土地基地质灾害 ,总结出高速公路软土地基勘测应选用合理的手段 ,提出勘测设计指标的确定应以十字板。Based on the problems arising in the geological engineering of the soft soil foundation on a certain expressway construction in Jiangsu Province, this paper provides a profound analysis on and inquiry into the engineering geological conditions in the area, soft soil distributing regularity, the property of its distribution and mechanical properties of soft soil layers on some typical parts of the expressway construction The paper also offers a summary on the variation thickness of soft soil layers in vertical sections, the great differences between the designed parameters and that provided by experiments.These are the causes which have brought about geological hazards with soft soil foundation on the coastal expressway construction. By comprehensiv comparation on the geological hazards arose by soft soil foundation on coastal expressway construction, the authors summed up that should appling feasible means in prospecting soft soil foundation on expressway construction, and put forward that the designing and prospecting surggested parameters should be determined according to the results of cross board and on the spot CPT experiments in the paper.
