通过模型试验实测了作用在大直径圆筒岸壁上的内、外土压力强度及其位移,对理入式圆筒结构的稳定性进行理论探讨,并提出稳定性计算公式。 Through the model test, the inner and outer soil pressure intensities and displacements acting on the large diameter cylinder wall were measured. The stability of the pipe-in-pipe structure was theoretically discussed and the formula for calculating the stability was proposed.
