摘要
依托青岛李沧区具体工程实例,克服以往相关研究的缺陷,配合系统的原位测试和室内试验,通过数理统计分析,从基本工程性质和软化特性两个方面,开展了对青岛李沧区不同风化程度煌斑岩工程性质的研究。结果表明:与相应风化程度的其他常见基岩比较,强风化煌斑岩基本工程性质衰减幅度最大,中风化煌斑岩次之,微风化煌斑岩衰减幅度最小;中风化、微风化煌斑岩饱和吸水率Wsat与软化系数K之间分别存在较为明确的指数函数关系、线性函数关系。
This paper that relies on Qingdao Licang area concrete engineering example has launched the research of lamprophyre engineering properties based on different weathering degree in Qingdao Licang area by two aspects of basic engineering properties and softening characteristic.In the foundation of overcoming the defects of past relative researches,this paper mainly depends on systemic in-situ tests,laboratory tests and mathematical statistics analyses.The results show that:If different weathering degree lamprophyre compared with other common different weathering degree bedrock,highly weathering lamprophyre basic engineering properties would weaken in greatest degree,and moderately weathering lamprophyre would weaken in greater degree,and slightly weathering lamprophyre would weaken in lest degree;There are specific exponential function relation,linear function relation between coefficient of water saturation Wsat and coefficient of softening K for moderately weathering lamprophyre,slightly weathering lamprophyre respectively.
