哈尔滨绕城高速公路软土地基的主要技术指标确定

Dertermination of the Main Technical Indexes for Soft Foundation of Harbin Round - the - city Expressway

对研究路段做了的钻孔勘察、土工原位试验和取代表性试样的室内试验,对土的物理性质、力学性能、压缩固结等主要指标进行了分析。结果表明:该路段上部土层分布不均匀,厚度变化大,密实性差,天然孔隙比大,且天然含水量较高。因此,必须对该路段进行有效的地基加固处理。本次的分析研究为该路段地基进行加固处理提供了参考依据。

Through much laboratory work of boring, soil undisturbed experiment and laboratory testing of field samples, the au-thors analysed the soil physical property, soil mechanics performance and condense data. The solution indicates that the superstructure of this highway segment distributes unhomogeneously, the soil thickness changes greatly, and the soil layer has high water content. Therefore the unsound foundation of this highway segment must be dealt with effectively. This anal-ysis provides a reference for foundation reinforcement.
