並且根據高藻期超濾處理沉澱池出水通量下降的規律，提出了超濾運行的最佳工藝參數，即水溫30時初始透膜壓力，水力反沖洗周期，化學清洗周期分別取0 . 07mpa ， 40min ， 330min ;水溫20時以上數值分別為0 . 07mpa ， 60min ， 960min 。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。Conclusions as following have got through test study : ( 1 ) when impact compaction technology is applied to treat collapsible loess subgrade, the effect depth may be treated generally can not override 80 cm and impact compaction pass is optimum at 30 times. ( 2 ) for stratified impact compaction of subgrade, when compactness of each level reaches codeslstandards loose laying depth of 80 cm fits 40 impact compaction pass is the optimum combination of subgrade construction. when average compactness in each level reaches codeslstandards loose laying depth of 80 cm fits 30 impact compaction pass is the optimum combination o ( 3 ) the quality control method may request impact compaction pass as the main control index and at the same time the final division settlement is less than 10 % of total settlement as large area subgrade is constructed
通過試驗研究主要得出如下認識：沖擊壓實技術處理濕陷性黃土地基時，其有效處理深度一般不超過80cm ，沖壓遍數以30遍左右為宜；對路基分層沖壓，在要求土體中各點壓實度均達到規范要求時，路基沖壓最佳組合為虛鋪厚度80cm 、沖壓40遍；在只要求土體平均壓實度達到規范要求時，路基沖壓最佳組合為虛鋪厚度80cm 、沖壓30遍；大面積施工時，質量控制方法可按照在以沖壓遍數作為主要控制指標的同時，要求最後10遍分計沉降量小於累計沉降量10 ；在施工單位自己購置沖擊壓實機情況下，與傳統施工相比較，沖擊壓實技術是一種既能節約資金又能大量縮短工期的施工方法。By using the constitutive model, we can establish the creep and consolidation model, the variation trend of super pore water pressure and the development of viscoelastic settlement and viscoplastic settlement. at last forecasting the long term creep settlement in the metallurgy industrial estate at the backward position of haihe river in tianjin
並利用此本構關系建立蠕變與固結模型，計算出土層在大面積填土作用下超靜水壓力發展趨勢，同時得出其粘彈性、粘塑性沉降發展趨勢，最後對冶金工業區軟土長期蠕變沉降作出預測。The climate of this period is almost as warm and wet as the stage 5e of the last interglacial. the mean temperature is 2 - 4 c higher and the precipitation is much larger than that of the today, the holocene which we live in. while in the climatic records of deep ocean, antarctic and greenland ice - core, marine isotope stage ( mis ) 3 is a weakly warm period, though a little warmer than marine isotope stage ( mis ) 2 and marine isotope stage ( mis ) 4, evidently colder than the last interglacial and holocene favorable period
末次冰期中期，即深海氧同位素第3階段的氣候在我國，尤其是青藏高原地區表現出明顯不同於深海沉積物和極地冰芯記錄的特徵：青藏高原古里雅冰芯的~ （ 18 ） o曲線表明3階段存在特強夏季風事件，其氣溫和降水接近於末次間冰期5e階段，超過全新世，其暖濕程度已經達到間冰期的程度；而深海氧同位素3階段在深海、南極、格陵蘭冰芯的氧同位素記錄中均為弱暖期，雖較2階段、 4階段溫暖，但顯著低於全新世大暖期和末次間冰期。Criterion method of settlement calculating is also introduced in this paper. after comparing the calculating value of criterion method with the data which measured in - site, this paper points out : ( 1 ) settlement brought by side deformation should be taken into account among the super soft silt groundsill in pearl river delta area ; ( 2 ) stress history has a great deal influence to the settlement, but the pre - consolidation pressure pc for the judgement of consolidation state of soil has no credibiliy which is gotten in laboratory
此外，本文還簡述了規范推薦的沉降計算方法，並運用已有的工程實測數據與規范方法計算值進行了比較，指出對于珠三角地區的超軟弱地基。應考慮側向位移引起的沉降；應力歷史對沉降的影響較大，而判斷土體固結狀態指標的前期固結壓力p _ c ，在試驗室得出的數據並不可靠。分享友人
