中华人民共和国许多大型水工建筑物计划修筑在河流的下游,那里的冲积层是由均匀饱和的细砂组成的,在这样地基上修建建筑物是与下列一些特点联系着的:当砂的密度、它的应力状态以及动力载荷结合的不利情况下,地基内的均匀细砂就可在某些时间内变成液化状态和具有类似粘性流体的性质,即是该砂土的抗剪强度实际上等于零的状态。用均匀细砂筑成的土工建筑物边坡上在其结构疏松的状态下,在边坡的角度不足时也可
Many large-scale hydraulic structures in the People’s Republic of China are planned to be built downstream of rivers where the alluvium is composed of uniformly saturated fine sand. Buildings on such foundations are associated with the following features: When sand density In the unfavorable combination of its stress state and dynamic load, uniform fine sand in the foundation can become liquefied and have properties similar to viscous fluids in some time, that is, the shear strength of the sand is actually Equal to zero state. The slope of the geotechnical building constructed with uniform fine sand can also be used when the slope of the slope is insufficient due to its loose structure.
