Based on the Stroh-type formalism and the technique of conformal mapping, the problem of two non-symmetrical collinear cracks emanating from an elliptical hole in a piezoelectric solid is investigated under remotely uniform in-plane electric loading and anti-plane mechanical loading, which allowed us to take the electric field inside the hole and cracks into account. The analytical solutions of the field intensity factors and the energy release rate are presented in closed-form, which includes the extreme cases for an impermeable crack and a permeable crack. Numerical results are then presented to reveal the effects of geometrical parameters, crack permeability and combined mechanical and electric loadings on the energy release rate.

针对基坑支护中深层搅拌桩墙围护结构出现的开裂,采用Mindlin厚板理论对其受力与变形性状进行弹塑性分析,建立了墙体的厚板力学模型和三维有限元分析模型,并编制了有限元分析程序;基于墙体受到纵向弯矩、横向弯矩和扭矩的综合作用,提出采用等效弯矩法评价墙体的综合抗弯性能;利用所编制的程序,获得了某基坑深层搅拌桩墙围护结构墙体水平位移和等效弯矩的空间分布规律;计算结果表明,墙体东侧环球广场横向支撑附加力的作用是使墙体形成破裂面的主要原因。
