It is shown that the friction force and bulkhead thrust are the main factors of shield thrust setting, while the friction between the cutterhead and soil is the main factors of cutterhead torque setting. Friction force between shield and soil would make front soil of shield upheave, and subsidence of surface soil is induced by ground loss when the friction force between the cutterhead and soil results in the surface settlement asymmetrical distribution.

通过计算发现，盾构施工中盾壳摩擦和正面推力是盾构推力设置的主要因素，而刀盘与土体摩擦是刀盘扭矩设置的主要因素，盾构前方土体隆起主要由盾壳摩擦引起，刀盘摩擦作用主要引起地表沉降的非对称分布，地表沉降主要由盾尾空隙产生。
