结果表明，多断层的力学场与单一断层的力学场相差甚远，在断层间形成了影响区。
The results show that. (1) The mechanical fields around these faults are very different from those of a single fault;
如果外载均匀，则展开式系数自前几项后为零，从而可得弹性层力学场量封闭形式的表达式。
When the external loads are uniform, the expansion terminates after some leading terms, and an explicit representation for the mechanical field in a layer is obtained.
对埋入混凝土的传感光纤而言，刚性保护构件的存在会对光纤周围的微观力学场产生扰动，从而影响光纤传感精度。
For sensing fiber embedded in concrete, the rigid protecting structure will disturb micro-mechanic filed around fiber, thus affect its measuring accuracy.
