巖溶化模式 的英文怎麼說
中文拼音 [yánrónghuàmóshì]
巖溶化模式
英文
karstification model-
Study on granular structure in laterite vn soil has already been reported in different land use pattern but it is little about soil fertility in karst environment. the better the soil structure, the higher the content of water - stable soil aggregate so there is an osculation correlation between aggregate and structure of soil
不同利用模式下紅壤團粒結構的特徵研究己有報道，但關于巖溶環境中土壤變化的研究則很少。土壤團聚體與土壤的結構密切相關，團聚體含量高，則說明土壤結構好。In this paper, combined with the research project " study on the design, construction and quality monitoring of foundations in karst and mined - out regions along tanshao highway " financed by the department of communication of hunan province, a deep analysis has been made to find out the factors influencing the safe thickness of bearing stratum under the pile tip in karst region. three simplified models are set up to calculate the safe thickness, from which empirical calculation formulas are deduced. and a few important conclusions drawn from the discussion can be used to guide engineering practice, which are also valuable materials for the revision of current criterions later
本文結合湖南省交通廳「潭邵高速公路巖溶及采空區路、橋基礎設計施工與質量監控方法研究」研究課題，以潭邵高速公路為工程依託，通過深入分析巖溶區基樁樁端持力層安全厚度的影響因素，提出了樁端持力層安全厚度計算的三類簡化模型，以此為基礎，推導出了樁端持力層厚度計算公式，並通過討論得到了可用於指導工程實踐的幾點重要結論，可供今後規范的修改參考；本文針對巖溶地區的特殊情況，提出了巖溶區樁基設計方法及具體設計步驟，並借鑒國內外巖溶區樁基的成功經驗，提出了巖溶區樁基設計處理幾種特殊方法，可供同類工程借鑒；另外，本文通過具體的工程實踐，系統總結了巖溶區樁基施工技術及常遇問題的處理方法。The results demonstrate that the pingba red residua is a typical in situ chemical weathering crust, and the material sources of the profile are derived from underlying triassic dolomites, the chemical weathering of dolomite can be divided into two stages : " leaching - accumulating trend " and weathering trend ", the stable teconic and whole weathering of dolomite should be the main reason for the development of thick and consecutive red weathering crust overlying dolomite rock in central guizhou
結果顯示該剖面是下伏基巖白雲巖風化成土並累積的結果，無其他外來物源，是原位風化殼；成土過程具有兩階段模式特徵，即白雲石、方解石的溶蝕酸不溶物累積和酸不溶物進一步風化兩個階段；長時期的構造穩定和白雲巖整體溶蝕作用是黔中地區白雲巖風化殼土層厚度大、分佈連續的主要制約因素。( 5 ) several group experimental result of solute transport in fractured medium was analysed in different direction. an experience formula of nacl solution was summarized, which changed in different position. the coefficient of advective - dispersive was deduced by means of back analysis based on the experimental results, which suited to solute transport in a single fracture of rock
（ 5 ）通過裂隙中溶質運移的多組實驗結果進行橫、縱向的比較分析，總結出了nacl溶液濃度沿程變化的經驗公式；結合實驗結果針對所推導出的數學模型擬合出適合單裂隙巖體的溶質運移彌散系數。分享友人
