【摘要】 弹性损伤与考虑残余变形的损伤模型是目前混凝土坝损伤分析中常用的两种模型。本文将两种损伤模型应用在Koyna重力坝破坏分析中,比较了两者模拟的开裂范围和裂缝张开度。计算结果表明:弹性损伤模型计算所得坝体的开裂范围和裂缝张开度均小于考虑残余变形损伤模型计算所得结果。弹性损伤模型计算所得结果偏于不安全。更多还原

【Abstract】 Elastic damage model and damage model considering residue deformation are two commonly used models for seismic damage analysis of gravity dams.They were used to calculate crack range and opening width in the seismic analysis of the Koyna dam and their computations are compared.The results show that the crack range and maximum opening width computed with the elastic damage model are smaller than those with the damage model considering residue deformation.Thus,the simulation results with the elastic damage model are unsafe.更多还原
