雷州半岛北海组泥质砂层工程特性试验研究

Research On Project Property Test Of The North Sea Group Muddy Sand Of The Leizhou Peninsula

雷州半岛中北部区广泛被第四系中更新世(Q2)北海组洪冲积层覆盖,其岩土类别主要为泥质砂层。对此,结合工程建设需要,对其工程特性进行广泛、深入的试验研究,全方位揭示其级配特点、密实度、渗透性、渗透破坏及地震液化等特性,对指导该地区工程建设、岩土工程勘察、水文地质勘察有较高的参考价值。

The north central of Leizhou Peninsula is widely covered with Middle Pleistocene North Sea group alluvial deposit,whose soil type is mainly muddy sand.Taking into account of the requirements of project construction,this paper makes a broad and deep research for the project properties and fully reveals gradation characteristics,compactness,permeability,seepage failure,earthquake liquefaction and so on.It has a high reference value to guide the construction,geotechnical investigation and hydrogeological investigation of this area.
