In order to test the structural performance for the bridge of Linxi 9th road project, the static test of precast prestressed concrete bridge hollow slab was carried out by four stage static loading method. Under the condition of elastic working, the flexural bearing capacity, crack propagation and relative residual displacement of the main control sections of the hollow slab are mainly investigated. The results of static loading test show that, when the efficiency of static loading test is 97%, the structural calibration coefficient, residual displacement of main measuring points and crack propagation meet the requirements.
