摘要

推导了平面P波斜入射时半圆形凹陷场地不同位置处土体应力的计算公式,分析了表面土体的位移幅值和内部土体的动应力路径,并比较了半圆形凹陷场地与半无限场地之间的差异。
        The calculation formula of soil stress at different positions of semicircular canyon site at oblique incidence of seismic wave is derived,and the displacement amplitude of the surface soil and the dynamic stress path of the internal soil are analyzed when the plane P-wave is incident,and the difference between semicircular canyon site and semi infinite site is compared.
