摘　　要：详细探讨了湾区软土层的特性及其潜在风险,揭示了处理软土地基的重要性和遵循的基本准则;结合具体的工程实例,研究与河涌同时施工的大厚度软土路基的有效处理方式,结合项目的紧迫性、经济性以及设计要求提出了2种的河涌护岸+路基处理方式:(1)河涌侧向约束支护(预制混凝土板桩)+路基采用轻质泡沫混凝土;(2)河涌护岸采用浅埋式支护(素混凝土墙+松木桩)+路基采用复合地基法(水泥搅拌桩),并分别对两种组合方式进行了整体稳定性的定量评估和完工后的沉降量计算(针对道路中心线),并将这些理论应用到了实际的工程操作中。充分发挥本方案的实用经济性,为河网密布的湾区工业园道路建设提供实际且有效的参考。The characteristics and potential risks of soft soil layers in the Bay Area are discussed in detail,and the importance of treating soft soil foundations and the basic principles to be followed are revealed.Combined with the specific engineering examples,the effective treatment methods of thick soft soil subgrade constructed at the same time with the river are studied.Two methods of bank protection+subgrade treatment are proposed combined with the urgency,economy and design requirements of the project,which are the lateral constraint support for river(precast concrete sheet piles)+light foam concrete for subgrade,and the shallow buried support(plain concrete wall+pine pile)for riverbank protection and the composite foundation(cement mixing pile)for roadbed.The overall stability of two combination methods is quantitatively evaluated and the settlement after completion is calculated(for the road center line),and these theories are applied to the practical engineering operations.The practical economy of this scheme is fully played,which provides the practical and effective reference for the road construction of the Bay Area Industrial Park with dense river networks.
