The Mitigation mechanism of dip rock slope and anaclinal slope are mainly discussed in this paper. Preliminary analysis was made with innovative physical model tests. In terms of technology governance mechanism, this study mainly used 3D printing of its complex components, including rock anchor and models of retaining wall, added physical model of rock slope which simulated by grindstone. The main incentive of model failure is assumed to be self-weight of the slope and rainfall infiltration weakening the rock's shear force, the process has been recorded. In addition, this study also observed the interaction between rock slope failure mechanisms and technology governance. The 3DEC numerical simulation software is used for simulation comparison to monitor the behavior and interaction between each block and the governance technology, to assist the insufficient observation of physical model test.The results showed that when the rainfall infiltration of the dip slope physical model begins, sliding displacement of the slope occurred first, and the upper part of the rock layer began to uplift. When rainfall continues to infiltrate, the softening between joints causes the front end to be not restrained by the ground anchor, resulting in toppling failure. After the rainfall infiltration exceeds the anchoring section, the anchoring depth is insufficient, resulting in complete damage. Compared with numerical simulation, the results are quite consistent. The numerical simulation is used to analyze the diversity of the dip slope. The dip angle of the layer directly affects the stability of the slope, and the strength of the rock anchor indirectly affects the failure time of the model slope. In the part of anaclinal slope model, the governance technology of slope toe and slope surface is mainly used. The test and simulation results showed that the dip angle of the weak side of the anaclinal rock slope is related to the stability of the model slope. When the dip angle is close to vertical or horizontal, the change of the dip angle of the layer is small, and it is less easy for blocks to fall on the slope.Finally, this study also used numerical simulation to compensate the inadequate of physical models, so as to significantly reduce the efficiency of test preparation and monitoring of physical model tests, and more efficiently obtained the diversified and in-depth research results.

520 $a 本文主要針對順、逆向岩石邊坡，探討其採用的治理技術機制，並以創新物理模型試驗進行初步分析。治理技術機制方面，本研究主要利用3D列印其複雜構件，其包含岩錨及擋土牆模型，並加入由研磨石模擬之岩石邊坡物理模型。模型破壞誘因假設以邊坡自重及降雨入滲弱化岩體剪力強度為主，並記錄其過程。此外，本研究亦觀察岩石邊坡破壞機制與治理技術間的互制情形，並以3DEC數值模擬軟體進行模擬比對，監測各塊體與治理技術間之互制行為，以輔助物理模型試驗觀察之不足。研究結果顯示，順向坡物理模型降雨入滲開始時，邊坡首先發生滑動位移，岩層上方開始隆起。當降雨持續入滲後，節理間的軟化造成前端未受地錨束制段，產生傾倒破壞。降雨完全入滲超過錨定段後，因錨定深度不足，導致完全破壞。其中以數值模擬進行比對，其成果相當符合，並由數值模擬進行順向坡多樣性分析，層面傾角直接影響坡體的穩定性，岩錨強度則間接影響模型邊坡產生破壞時間。逆向坡模型部分，則以坡趾與坡面實施治理技術為主。試驗與模擬結果發現，逆向坡岩體弱面傾角與模型坡體的穩定性有關，當傾角接近垂直或是水平時，層面傾角變化量較小，坡面上也較不易有塊體的掉落。最後，本研究亦使用數值模擬輔助物理模型之不足，以大幅降低物理模型試驗的試體準備與監測效率，更能有效率獲得多樣化且深入的研究成果。.
