滑坡災(zāi)害是影響人類生命與財產(chǎn)安全的重大地質(zhì)災(zāi)害之一,而在我國的三峽庫區(qū)其發(fā)生尤為頻繁。因此,對滑坡變形的機理展開深入研究具有重要的實際意義。一般而言,分析滑坡的穩(wěn)定性是通過現(xiàn)場取樣、室內(nèi)或原位試驗（直剪、三軸等）的手段獲得巖土體的抗剪強度參數(shù),從而進一步計算得到滑坡的安全系數(shù)。由于場地條件的限制,開展原位試驗通常只能針對滑體部分進行,而無法對滑帶部分進行有效的測試�；瑤强刂苹聠右约斑\動過程的關(guān)鍵結(jié)構(gòu),其結(jié)構(gòu)與強度通常與滑體有較大差異;因此,對滑帶開展原位試驗理論上可以反映出更為真實的滑坡穩(wěn)定性狀態(tài)。目前,蠕變試驗是研究巖土體長期變形與強度性質(zhì)的唯一途徑。對于尚未發(fā)生或正在經(jīng)歷緩慢變形的滑坡而言,開展原位蠕變試驗?zāi)軌蛘鎸嵙私饣瑤恋淖冃翁匦?從而對滑坡穩(wěn)定性評價與預(yù)測提供更加合理的依據(jù)。黃土坡滑坡是三峽庫區(qū)已探明的最大規(guī)�；�,根據(jù)監(jiān)測數(shù)據(jù)可知,該滑坡長期處于緩慢變形過程（滑坡前部地表位移約30 mm/年）;滑帶的埋深深度約50-70 m,由于長期上部荷載的影響,滑帶結(jié)構(gòu)致密,與重塑樣有明顯區(qū)別。基于上述特征,本文針對黃土坡1號滑坡（黃土坡滑坡變形最大的子滑坡）的滑帶土開展了原位蠕...
