| description | To explore the accuracy of the calculation method of the jacking force of circular curved pipe jacking under different pipe-soil contact characteristics, in combination with the curved steel pipe jacking project of Gongbei Tunnel of Hong Kong-Zhuhai-Macao Bridge, this paper adopted several commonly used jacking force calculation formulas for the curved pipe jacking at home and abroad and jacking force finite element analysis model with consideration of grouting effect and the pipe-soil contact range established with ABAQUS to calculate the jacking force. It was found by contrast with the pipe jacking force data: ①The calculated value of jacking force: JMTA formula≫Shanghai normative formula>Shimada formula, where it was considered that the calculated value of the lower limit of Shimada formula of 1/3 pipe-soil contact was relatively close to the measured value. ②Through numerical simulation, it was found that the simulated jacking force of 1/3 pipe-soil contact characteristics was gradually close to the one of 1/2 pipe-soil contact characteristics; in the grouting state, the previously measured jacking force was close to the one of 1/2 pipe-soil contact characteristics. When the jacking force tended to be stable, the measured jacking force was close to the one of 1/3 pipe-soil contact characteristics. Therefore, the numerical model could predict the jacking force of the pipe jacking under the same working condition and had a certain guiding significance for actual construction. |
