- The main achievements are obtained as follows in the paper : ( 1 ) the deformation fracture of the left bank ' s hypergene reform is mainly consisted of slipping pressure pull crack slipping flexure slipping pull crack and dumpping pull crack . the right bank , is the slipping pull crack .
论文获得的主要成果如下： ( 1 )左岸浅表生改造的变形破裂机制主要有滑移压致拉裂、滑移弯曲、滑移拉裂和倾倒拉裂等。右岸浅表生改造主要表现为滑移拉裂式的变形破裂为主。 - ( 2 ) according to the forming model of the deep pull cracks , they can be divided into three classes pulled cracks - , pressed cracks and sheared cracks . ( 3 ) based on the two - dimensional and three - dimensional finite element methods . the following results can be affirmed : in the slope excavating process , the base surface will rebound in the direction of the excavating surface ' s excerior normal . the maximal displacements of the left and right bank are + 3 . 6cm and + 2 . 4cm ; the arch abutment will rebound in the direction of the river valley , the maximal displacements of the two bank are + 3 . 5cm and + 2 . 2cm ; the upstream and downstream surface will rebound in the direction of the normal direction . the maximal displacements are + 2 . 1cm and + 1 . 7cm . ( 4 ) the natural slope is stable
( 3 )通过二维及三维有限元分析得知，左右岸拱肩槽边坡在开挖过程中，开挖底面主要表现为朝开挖面外法线方向发生回弹，左右岸最大位移量分别为+ 3 . 6cm 、 + 2 . 4cm ；拱端面主要表现为向河谷方向发生侧向回弹，左右岸最大位移量分别为+ 3 . 5cm 、 + 2 . 2cm ；上下游坡面主要表现为向临空方向的回弹，左右岸最大位移量分别为+ 2 . 1cm 、 + 1 . 7cm ；开挖使岩体产生由卸荷回弹导致的倾倒拉裂现象。
