摘要
本文利用土力学、土动力学及地下水动力学中的有关原理 ,对砂土液化发生机制进行分析 ,提出了液化临界超静孔隙水压力随地震持续时间及埋深等内外因素变化的关系 ,并利用该理论对唐山地区液化的特征进行了分析研究 ,并且与实际资料作了比较。
Mechanism of sand liquefaction is analyzed by using the principles of soil mechanics, soil dynamics, and groundwater dynamics. Relationship of variation among critical ultra\|static pore water pressure of liquefaction and the duration of earthquake and embedded depth are proposed. The characteristics of liquefaction in Tangshan district are studied with the said theory and compared with the data.
