摘要:

为研究高强混凝土在常规三轴压缩状态下的能量演化规律与整体破坏行为,开展了5组不同围压下C60和C70高强混凝土常规三轴压缩试验。基于试验结果和热力学能量守恒原理,得到高强混凝土输入能密度、弹性应变能密度和耗散能密度随轴向应变和围压的变化规律,并根据高强混凝土峰值应力对应的弹性应变能密度与围压成线性增长关系,建立了基于弹性应变能密度的高强混凝土破坏准则。研究结果表明:①高强混凝土输入能密度和耗散能密度均随轴向应变的增大而增大,弹性应变能密度在峰前阶段随轴向应变的增大而增大,峰后随之减小;②高强混凝土峰值应力对应输入能密度和耗散能密度均随围压的增大而增大,且同等围压条件下C70高强混凝土峰值应力对应的输入能密度和耗散能密度均大于C60高强混凝土;③基于弹性应变能密度的高强混凝土破坏准则精度高、所含参数少且物理意义明确,该准则表达形式与Hoek-Brown破坏准则相似,但其适用性更加广泛;④高强混凝土破坏准则在π平面为等边不等角的对称六边形,根据“化角为弧”的方法对破坏曲线奇异点进行了圆化处理。本文研究结果可为从能量角度研究混凝土材料变形破坏行为提供新的思路。

Abstract:

In order to study the energy evolution law and failure behavior of high-strength concrete under conventional triaxial compression state, five groups of tests of C60 and C70 high-strength concrete under different confining pressures were carried out. Based on the test results and the principle of thermodynamic energy conservation, the variation laws of input energy density, elastic strain energy density and dissipation energy density of high-strength concrete with axial strain and confining pressure were obtained. According to the linear growth relationship between elastic strain energy density corresponding to peak stress of high-strength concrete and confining pressure, the failure criterion of high-strength concrete was established. The results have shown that:① The input energy density and dissipated energy density of high-strength concrete increased with the axial strain, while the elastic strain energy density increased with the axial strain in the pre peak stage and decreased after the peak;② The input energy density and dissipated energy density corresponding to the peak stress of high-strength concrete sample increased with confining pressure, and the input energy density and dissipated energy density corresponding to the peak stress of C70 high-strength concrete were greater than that of C60 high-strength concrete under the same confining pressure;③ The failure criterion of high strength concrete based on elastic strain energy density has high accuracy, few parameters and clear physical meaning. The form of the criterion was similar to Hoek-Brown failure criterion, but it has wider applicability;④ The failure criterion of high-strength concrete was a symmetrical hexagon with equal edges and unequal angles in the π plane. The singular points of the failure curve were rounded according to the "turning angle into arc" method. The research results provide a new idea for studying the deformation and failure behavior of concrete materials from the perspective of energy.
