Based on the principle of superposition of linear elastic fracture mechanics,this paper derives the approximate analytical expressions of stress intersity factors (KI) at the crack tips of axisymmetric fractures emanating from cylindrical holes with hydraulic fracturing under in -situ stress field and fluid pressure.
本文根据弹性断裂力学的叠加原理,建立了地应力场和流体压力作用下水力压裂中孔边轴对称裂纹尖端应力强度因子K_1的近似解析表达式。
