Abstract: The inclined boom with waist cables of rivers of high velocity discharge is a structure of new type.The structure was first initiated by the Chinese technicians in wood water transport.This article deals with the process of a hydrotechnical model test of the inclined boom with waist cables and the measurement results.The experimental data prove that the inclined boom with waist cables is reasonably designed in terms of structures and ensured safely in construction.The design load is basically in conformity with the measured value subjected to the force of the boom. Hydraulic model test by way of the new testing technique and new data-processing method has raised the measuring technical standards of the hydrotechnical model test.
