砂擾動
英文
disturbance of sand-
The sandstone shows a more persistent oscillation.
砂巖表示一個更為持久的擾動。X-radiography has sometimes been used with success to detect bedding structures and bioturbation in apparently uniform sandstone.
X射線照片有時已成功地用來發現外表均一的砂巖中的層次構造和生物擾動。X - radiography has sometimes been used with success to detect bedding structures and bioturbation in apparently uniform sandstone
X射線照片有時已成功地用來發現外表均一的砂巖中的層次構造和生物擾動。Granite blocks, coral reef blocks, sandstone, bricks and glass fragments can be seen. these materials were there probably due to artificial reasons
可見花崗塊、珊瑚礁塊、砂巖塊及磚瓦、玻璃等物分佈，這些遺物應為外力堆放擾動所致。Finally, two examples show that, the availability and practicability of the new model is verified. the analysis of calculation result of berthiervill test embackment shows different part of compression curve have different influence upon the course of consolidation, and correct coefficient and viscous effect have great significance on deformation forecast. associated with the wenzhou airport runway engineering, the reason of increasing of pore - water pressuer in under - lying soft layer and post - construction settlement are given
最後，通過兩個工程實例的分析來說明本文模型的有效性和實用性:一是對berthiervill填土試驗場的軟基實測數據和理論成果進行對比分析，闡明考慮結構性擾動和粘滯性效應對分析天然粘土固結壓縮性的重要性;二是對溫州機場袋裝砂井超載預壓工程進行數值模擬，指出停荷預壓期間下臥層孔壓增加和工后沉降大的原因。According to unsaturated soil strength theory presented by fredlund, we have taken lead in establishing a formula of soil strength in beijing area ' s layers taking into consideration matric suction and the relationship between water content and matric suction. the change of water content is also a kind of disturbance from board angles
在國內，針對北京地區粉質砂土，根據fredlund提出的非飽和土強度理論，率先建立了考慮基質吸力影響的土的強度公式；吸力與含水量密切相關，從廣義擾動角度來說，含水量的變化也是對土的擾動。After re - exploration and careful analysis ， it was found that the sand soil under the bottom of the pile and around the pile was disturbed during the construction of cfg piles
通過驗證勘察並經綜合分析后認為，造成單樁承載力不足的主要原因是施工時擾動了樁底或（及）樁周砂層。分享友人
