( 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 ）通過二維及三維有限元分析得知，左右岸拱肩槽邊坡在開挖過程中，開挖底面主要表現為朝開挖面外法線方向發生回彈，左右岸最大位移量分別為+ 3 . 6cm 、 + 2 . 4cm ；拱端面主要表現為向河谷方向發生側向回彈，左右岸最大位移量分別為+ 3 . 5cm 、 + 2 . 2cm ；上下游坡面主要表現為向臨空方向的回彈，左右岸最大位移量分別為+ 2 . 1cm 、 + 1 . 7cm ；開挖使巖體產生由卸荷回彈導致的傾倒拉裂現象。 -
