摘要
In order to solve the towing problem on water of the open caisson in the construction of the large scale bridge efficiently, combining with the towing operation project, the dragged open caisson and environmental data, etc. we design and produce the open caisson physical model and configure the test environment, use the force cell to collect real-time experimental data, analyze and demonstrate the towing resistance of the open caisson. Use the experimental data and the model of resistance similarity transformation to calculate the resistance, while the towing speed is 1m/s, 2m/s and 3m/s, the resistance is 323 KN, 724KN, 1398KN in the straight test mode and the resistance is 365 KN, 861KN, 2326KN in the transverse test mode. The results show that the resistance of the open caisson has certain growth trend with the towing speed rising, which both have large correlation, and the resistance of transverse situation is larger than straight mode. © 2015, Hongjun Chen; Licensee Bentham Open.
