| 中文摘要:青岛龙湖D2地块基坑支护工程中，支护桩对应土层为素填土、粗砂、粉质粘土。采用PRC-I 600AB110单节预应力管桩作为支护桩，桩径600 mm，桩长分别为7 m和8 m，桩端进入粉质粘土地层约3 m深。该桩刚度大，施工速度快。基坑开挖后，坡顶地面未出现明显裂缝和沉降。基坑经过监测，水平、竖向位移等监测项目均在允许位移范围内，满足设计要求。 |

| Abstract:In the foundation pit support engineering in Longhu of Qingdao, the retaining piles are set in soil layers of plain fill, coarse sand and silty clay. PRC-I 600AB110 single pre-stressed pipe pile, with high stiffness, was adopted as retaining pile, the pile diameter is 600mm, pile length are 7m and 8m respectively. After the excavation, no obvious cracks and subsidence appear in the ground at the top slope. The monitoring results show that the horizontal and vertical displacements of the foundation pit are within the allowable ranges, the construction has met the design requirements. |
