坡腳開挖 的英文怎麼說
中文拼音 [pōjiǎokāiwā]
坡腳開挖
英文
toe excavation-
And combining with compound analysis, this thesis has calculated and estimated the deformation and stability of slopes of the cliff debris and residual soil slope project on the project site at k15 + 183 of yong ' an section of yong - zhang highway ; ( 3 ) in the course of the cut slope excavation inner displacement has been in control of real time field monitoring
同時邊坡開挖後期坡頂會出現回彈現象。 3 、數值計算成果表明，隨著開挖階數的增加，大小主應力在邊坡內也進行不斷的調整。邊坡開挖后坡腳處大小主應力值nlfep程序結果與ansys計算結果較為相似，兩者吻合性較好。It reveals that the slope stability is mainly controlled by a set of joingts nearly parallel to the slope surface with a moderate to gentle dip angel. obvisouly, its persistence ration is the most important factor among all th e charatcteristics related to the stability analysis. on the other hand, the nature slopes and the excavated ones show a series superficial deformation and failure phenomena related to unloading process and time - dependent deformation, which are all described and recorded in detail in author ' s work
經過現場地質調查發現，邊坡中一組sn向中緩傾角結構面對邊坡的失穩具有控制意義，它的存在導致了邊坡可能的失穩模式為平面滑動，即當坡腳被剝蝕或進行切腳開挖時，發生沿邊坡內sn向中緩傾節理滑移，沿后緣陡裂張開的一種滑動失穩模式。Topics include : site investigation ( with emphasis on in situ testing ), shallow ( footings and raftings ) and deep ( piles and caissons ) foundations, excavation support systems, groundwater control, slope stability, soil improvement ( compaction, soil reinforcement, etc. ), and construction monitoring
主題包含有工址調查（強調現地試驗） 、淺基礎（基腳式基礎與筏式基礎）和深基礎（樁基礎與沉箱） 、開挖之支撐系統、地下水控制、邊坡穩定、土壤改良（夯實與土壤加勁等）和施工監測等。Through contrasting the characteristics of stress field inside the slope before and after the excavation, the results show that the horizontal stress upside the slope and the shear stress pointing to the outside slope near the foot change clearly
通過對比開挖前後邊坡內部的應力場特徵，發現：在影響邊坡穩定的指標性應力中，邊坡上部的水平應力受開挖影響較大；在成坡坡腳附近，指向坡體外的剪應力顯著增加。By calculated and analysed of the lanedslide stability, it is conclused that the big fissure ， clayey sail of ground water - level fluctuation and digged base of slope formed an unstable slope
通過穩定性的定量計算與定性分析可知，坡體上的大裂縫與地下水變動帶在開挖坡腳處剪出聯合組成的滑面穩定性最差，此滑坡將來的滑動破壞剪出口將在開挖坡腳附近產生。分享友人
