最终得到如下结论：①小湾坝基开挖卸荷现象表现出多样性，并且在地貌特征和发生位置上具有明显的规律性；②结合河谷应力场特征，对小湾坝基开挖卸荷现象进行分析，并相应地提出了剪胀、纵弯曲张裂、错动板裂和上拱张裂等力学模式，合理地解释了小湾坝基开挖产生的卸荷现象；③板裂现象是高应力区发现的一种比较特殊的卸荷现象，它的产生需要比较苛刻的地质和力学条件。

For the composites with a low content of TiC particle, the rupture manner was mainly the nucleation of cavity and following ductility splitting fracture. But for the composites with a high content of TiC particle, the cracking and decohesion of TiC particles were the main rupture mechanism. For the composite containing a middle TiC content, the rupture mechanism consisted of the above two styles, but the former was the dominating mechanism and the later was the subordinate mechanism.

对TiC体积分数较低的钢基复合材料，拉伸过程中TiC颗粒界面上的孔洞形核及随后塑性撕开机制是其断裂失效的主要机制；对TiC体积分数较高的钢基复合材料，拉伸过程中TiC颗粒的开裂及脱落是其断裂失效的主要机制：对TiC体积分数介于上述两者之间的钢基复合材料，拉伸过程中TiC颗粒界面上的孔洞形核及随后塑性撕开机制在其断裂失效过程中占主要地位，而TiC颗粒的开裂及脱落占次要地位。

A meso mechanical analysis has been conducted on a hot-rolling steel of 16MnR toinvestigate the effect of the elongated pre-damage voids on the subsequent damage evolution and fracture process under the maximum normal stresses with various directions.
