前言饱和砂层的液化是造成土木工程震害的主要原因。评价土壤液化灵敏度的现有方法主要是以应力法为基础的,依赖于试验室内应力控制式循环荷载或现场贯入试验来测定或估算土壤的循环强度。这些循环强度的确 Preface Liquefaction of saturated sand is the main cause of seismic damage in civil engineering. Existing methods for assessing soil liquefaction susceptibility are based primarily on the stress method, which rely on stress-controlled cyclic loading in the laboratory or on-site penetration testing to determine or estimate soil cyclic strength. Indeed, the strength of these cycles
