( 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。Rock foundation excavation of fenhe erku project in shanxi province
山西省汾河二庫大壩樞紐工程岸坡及基礎巖石開挖In order to direct the water to the forebav of the pump station from the original canal, a channel long 135 m is designed. it crosses through the terrain top with a depth of more than 50 m. soil of the channel slopes is a strongly - weathered silty and sandy mudstone with many well - developed reticular cracks and takes the structural surfaces almost same as the channel slopes
東深供水工程金湖泵站位於塘廈鎮東面，屬低山、殘丘地貌，地面高程22 60m ；泵站前池進水渠橫切山脊，連接原東深供水河，設計開挖1條長135m的進水渠，坡高50多米，邊坡土質為強風化的粉砂質泥巖，網狀裂隙發育，結構面基本與坡面重合；坡體土質中含有較多的粘土礦物，具有遇水軟化的特性。The change regularities of lining pressure and the failure process of surrounding rocks in permeation which a special sand is used as model materials are successfully simulated. the basic theory is established for the study of same type and the scientific basis for the tunnel prop design in saturation rock is provided
採用特定的河砂作為模型材料成功地模擬了破碎圍巖隧道在遇水情況下襯砌的受力變化規律及巖體的破壞過程，為開展同類型研究奠定了基礎理論，為飽水巖體隧道開挖支護設計提供了依據。The key factors to make the slide is controlled to make the model be similar in geometry, material and fabric with the antetype, then simulate the infection of river, digging of road and so on, measure the data of the distortion of model, analyze the reason of the distortion and factors of the slide
試驗抓住造成滑坡的主要因素，根據所得的巖石力學參數及結構面參數，在幾何條件、模型材料、結構面條件等方面都基本滿足相似原理的情況下，對模型進行了河流下切、公路開挖等條件的模擬，測量觀察邊坡的卸荷回彈與層面的彎曲變形情況，利用所側數據分析論證滑坡的形成機制和影響因素。Water conservacy and hydroelectric projects being programmed or constructed in incised river valley of southwest and northwest of china all relate to weathered and unloaded rockmass. it is very important and significant to study weathering and unloading for engineering design, parameter value choosing, rockmass quality classificatioarockmass excavation, foundation plane choosing, even project running. the dissertation is based on granite rockmass in laxiwa hydroelectric station damsite, yellow river
規劃中或正在建設的西南、西北深切河谷區水利水電工程均涉及到巖體風化、卸荷問題，而研究巖體風化、卸荷對于工程設計、參數取值、巖體質量分級、巖體開挖、建基面選取乃至未來工程運行等具有重要意義。分享友人
