This article introduces the silt geology platform afterwards uses the powder spurts and the plastics drain off water the board and grille and back pressure protects etc design and the construction control of measure, the construction has the guidance meaning to the construction of the bridge abutment soft base
摘要介紹了淤泥地質臺后採用粉噴樁、塑料排水板、土工格柵、反壓護道等措施的設計與施工控制，對臺后軟基處治工程的施工有指導意義。 -
The pore water pressure dissipation in the silt is produced mainly by lowering of groundwater table and pore water pressure dissipation in the pvds ( or sand drains ) is produced mainly by vacuum degree
淤泥地基中孔隙水壓力消散主要是由於地下水位線的下降引起的；而砂井或塑排中的孔壓消散大部分由真空度直接引起。 -
The pore water pressure difference between silt and pvds ( or sand drains ) increases and the soil consolidation velocity is accelerated during the embankment construction
在路基填築期間，淤泥地基與豎向排水體之間的孔壓差增大，加速土體固結。 -
The famous project of gas transiting west to east and the cross - river tunnel of huangbu river in shanghai also will be constructed with this technique, which is under the plan. among the shield tunneling methods, up to now, earth pressure balanced shield tunneling ( epbs ) is the most universal type, and it is very certain that the epbs method adopt to our country increasingly. the key factor to success in epbs is converting the muck which is lack of fluidity excavated from the cutter face to the plasticity soil. but when the shied tunneling machine advancing, it is considerably difficult to reach this requirement because of the ground soil condition, which is consist of stiff clay, silt, weathered rock, and so on
近些年來我國城市地鐵建設迅速發展，盾構施工法作為一種安全而又環保的施工方法得到了廣泛的使用，另外在黃浦過江隧道，西氣東輸的穿黃隧道等工程也在使用盾構隧道施工技術。這其中土壓平衡式盾構在我國的使用最為普遍，成為地鐵隧道施工技術的主流。土壓平衡式盾構施工成功的關鍵是要將開挖面切削下來的土體在壓力艙內調整成一種「塑性流動狀態」 。 -
Basing on analysis of the situation of water resources in loess plateau areas, this paper propounded the engineering and agricultural technology and the method with direct and indirect, which draw rainwater on road surface into " soil reservoir " of farmland or water cellar with free atmospheric pressure using silt delve of eliminate energy
摘要通過對黃土高原水資源現狀分析，提出了採用消能淤泥坑，通過直接、間接將路面雨水引入農田「土壤水庫」或時空可調節的自壓式集流水窖等貯水設備中，並採用一定的耕作農藝措施將路面雨水利用到農田中的方法和技術。 -
On the basis of vibratory compaction test using silt, which is difficult to compaction and cement - stabilized soil, which is the most conventional semi - rigid material, the influence regularity of vibratory parameters such as amplitude, frequency, centrifugal force, intensity of pressure, time of vibratory and material factors such as water content is studied
研究了靜面壓力、激振力、頻率、振幅、振動時間等振動壓實參數以及含水量等材料因素對振動壓實效果的影響規律。根據各參數對振動壓實效果的影響規律，找出一套壓實效果好並且和現有振動壓路機的技術參數基本相符的振動參數，在此基礎上提出擬定道路材料振動壓實的試驗方法的參考意見。 -
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。
