The acoustic emission experiments of concrete under uniaxial tension loading in whole process are conducted arid the stochastic modeling theory is introduced to determine the random field distribution parameters of the limit fracture strain of the mesoscopic damage elements 利用混凝土单轴受拉破坏全过程的声发射实验数据，引入随机建模理论，确立了细观损伤单元的极限破坏应变随机场分布参数。
