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」 。 -
