    膨脹土是一種會給工程帶來嚴重破壞的高塑性粘土，特別是對高等級公路路基工程和大型結構物所產生的變形破壞作用，往往具有長期、潛在的危險。
  2. Researching on the technology if reverse order is to study strains if pits, structural systems if basement, environmental surwey and underpinnings. on account of emphasizing developing methods if checking strength if pick - ets, modemizing machenes of excavation and studying methods of underpinning is put forward and is a way if controlling the quality of pickets in sites, which leads an active effect ; synthetic application if rankintheory, spatial and time effect theory to excavation tl aanalyze the state of soil force and strain is brought forward and the time effect should be considered in the zone of clay, the formation and development of soil plasticity are analyzed and the most dangerous zone to decide how to excavate and where to begin is found ; analyzing the cause of picket settlement during reverse order and the differential settlement and discussing hlw to solute it. duringh the temporary survey and the environmental warship, bringing rorward the theory of environmental vibration and analyzing the state of soil force and probability of losing stabilization of soil under the effect of environmental vibration ; analyzing the state offeree in underground concrete wall by the method of mathematics and pointing out the place of the maximum force and deformation. based on systematic illustrating the reverse order, problems about application and development of reverse order and suggestions also are expressed

    鑒于國內外的研究把重點放在大力發展工程樁的實驗室承載力監測方法與設備、如何使土方開挖機械現代化及對周圍建築的臨測方法上，本文提出了現場利用聲波層析成像技術監測鋼砼樁內部質量的方法與程序，並得出了聲波層析成像技術是砼樁的動態質量檢測的有效手段，這對指導施有積極、現實意義；提出了綜合運用朗肯土壓力理論、基坑空間和時間效應影響理論來分析逆作法施工過程中基坑邊坡土體應力及應變的變化情況，指出粘土地區也應考慮時間效應，並且進一步分析了基坑邊坡土體的塑性區形成和發展，找出邊坡最不利的區域，以確定地下室土體的挖掘的方式和順序，指出憑主觀臆斷與經驗來施工是不可取的；在分析、經較逆作法與大開挖順作法的地下室結構體系受力情況及施工順序的不同，提出了節點處理技術；分析了逆作法施工期間樁的沉降變化原因及由此而產生的差異，並探討了解決的方法；本文還提出了環境振動對土體邊坡穩定產生影響的觀點，並分析了在環境振動影響下，土體的應力狀態及土休失穩破壞概率，並且還運用彈性力學知識和數學分析的方法定量地分析了地下混凝土墻受力狀態，指出了被監測墻體的最大應力、應變位置。
  3. 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」 。
