以上海浅部和深部土层变形数据、承压含水层变形和水位数据、基础设施（主要是地铁隧道、高架和地面道路）变形数据为基础，研究了上海深部土层、浅部土层变形特征和承压含水层变形机理，探讨了浅部、深部土层共同变形作用下地铁隧道、高架和地面道路的变形特征．研究结果表明：上海浅部土层持续缓慢压缩，压缩量较小，深部土层在2009年之前出现大幅度压缩，2009年之后逐渐出现膨胀变形特征；上海承压含水层变形与该土层水位高标有紧密的关系，第I、II、III和V承压含水层水位上升时，该土层很快出现膨胀变形，而第IV承压含水层膨胀变形滞后于该土层水位的上升；深部土层与基础设施有相似的变形趋势，不同厚度的浅部土层影响着基础设施的绝对变形量．距离深部土层越近的基础设施，伴随着深部土层的膨胀，其隆起量越明显；相同条件下，浅部土层越厚的基础设施其沉降量越明显．

Based on the shallow and deep soil deformation data, the deformation data of the aquifer and the water level, the deformation data of the infrastructure (mainly the subway tunnel, the elevated and the ground roads), we studied the deformation characteristics of the deep soil layer and shallow soil layer in Shanghai, and discussed the deformation characteristics of subway tunnels, elevated and ground roads under the combined deformation of shallow and deep soil layers, and reached the following conclusions. First, the shallow soil layers are in continuous compression, and the total amount of compression is small. The deep soil greatly compressed before 2009, and has gradually expanded since then. Second, the deformation of the confined aquifer in Shanghai is closely related to the water level of the soil layer. When the water levels of the first, second, third and fifth aquifer rise, the soil layer rapidly expands. The expansion of the fourth confined aquifer is lagging behind the rise of the soil water level. Last, deep soil layers have similar deformation trend with the infrastructure, and shallow soil layers with different thickness affect the deformation of the infrastructure. The infrastructure near the deep soil layer has obvious uplift deformation, accompanied by the expansion of deep soil layer. Under the same conditions, the infrastructure with thick shallow soil layer shows greater settlement than that with thin shallow soil.
