本文重點對真空堆載聯合預壓法的滲流進行了研究，得出了在分級加荷下軟土地基滲流量的計算公式，算例表明其計算值與實測值較吻合，說明所建模型是比較合理的。Abstract : the paper describes the application of vacuum preloading in combination with surcharge preloading to improve soft soils for la rge working load in the storage area of phase of nanjiang coal terminal of ti anjin port. analysis is made on the result of the improvement and it is concluded that the technique of vacuum proloading in combination with surcharge preloadin g can be used to improve soft soils for large working load and the result can be remarkable
文摘:本文介紹了大使用荷載條件下真空聯合堆載預壓技術在天津港南疆煤碼頭堆場（二期）軟基加固工程中的應用情況，並對加固效果進行了詳細分析，得出了大使用荷載條件下可採用真空聯合堆載加固軟基且加固效果明顯的結論。Some key subjects of numeric analysis were discussed such as : selecting principles of constitutive equations of soft clay, the equivalent theory of vertical drains ground, the definition of load step, the determination of vertical drains as well as the treatment methods of the decline of groundwater level, sealing wall and nearby water source
著重論述了真空預壓加固地基數值分析中對土體本構方程的選擇、砂井地基等效轉換、分析荷載步的確定、豎向排水體的界定、地下水下降的處理、密封帷幕的處理、附近補充水源的處理等問題。Then, combined with the mechanism of vacuum preloading and based on the layer method, settlement calculation of vacuum preloading was analyzed. the study shows that the vacuum degree under membrane equivalent load method does not accord with the mechanism of vacuum preloading. based on the layer method, vacuum degree difference method and effective stress method are presented. the results show that the final settlement calculated by the vacuum degree difference method is more close to the observation results
然後，結合真空預壓的機理，基於分層總和法的思想，對真空預壓沉降計算方法進行研究：指出用現有的膜下真空度等效荷載法進行沉降計算不符合真空預壓機理；提出了符合真空預壓機理的真空度差值法與有效應力法，前者所推算的最終沉降量較接近實測推算結果，後者與實際結果存在一定差距。( 8 ) for the sake of overcoming the shortage of the former work, axisymetrical analytical solutions of vacuum combined surcharge preloading were deduced, the effect of surcharge loading speed was considered and vacuum was regard as instantaneous load, so we can take account of effect of surcharge loading time, well resistance and smear, it is more closed to practical engineering
（ 8 ）根據以前真空-堆載聯合預壓解析解的不足之處，推導了真空-堆載聯合預壓下地基孔壓及固結度的解析解。本文的解析解將真空荷載視為瞬時施加，而將堆載荷載的施加考慮為線性施加過程，因此可以考慮堆載施加的時間影響，與實際工程情況更摘要加接近，並可同時考慮井阻、塗抹的影響。( 7 ) axisymetrical analytical solutions of vacuum preloading was deduced to compute pore water pressure and degree of consolidation, the effect of vacuum loading speed, well resistance and smear were considered
（ 7 ）在軸對稱單井模型的基礎上，推導了考慮真空荷載施加過程的真空預壓下地基孔壓及固結度的解析解，同時可考慮井阻、塗抹等因素。分享友人
