采用模型试验实测圆筒结构筒内土压力 ,并对圆筒在倾覆过程中筒内土压力的变化规律进行探讨。最后依据实测土压力图形提出筒内土压力计算公式
The model test was used to measure the earth pressure in the cylindrical structure cylinder and the variation of earth pressure in the cylinder during the tilting process was discussed. Finally, according to the measured earth pressure graph, the formula of earth pressure in the earth tube is proposed
