摘要
派克(Peck)理论由于计算简便,结果可靠,成为实际工程中常用估算盾构施工引起地面沉降的方法。该文以西藏南路越江隧道下穿M8线工况为例,采用派克(Peck)理论建立数学模型。通过监测点观察的数据与理论计算进行对照,验证了派克(Peck)理论对上海地区软土地层的沉降理论计算和实际监测结果十分接近。对于采用盾构法施工的隧道,预测地层的沉降,制定科学、有效控制沉降措施具有十分重要的意义。
Peck theory becomes the method to estimate the ground settlement caused by the shield construction commonly in the practical projects because of the simple calculation and the reliable result. Taking Xizhang (S) Road Crossing-river Tunnel underpassing M8 Line as an example, the article uses Peck theory to establish the mathematical model to carry out the comparison by the inspecting data at the monitor points and the theoretical calculation, and verify the Peck theory being very closing to the results of the theoretical calculation and the practical monitor of the settlement in the soft soil stratum of Shanghai. It is very significant to forecast the settlement of stratum and to work out the measures of scientifically and efficiently controlling the settlement for the tunnel construction by the shield process.
