8.0.1 The aim of load test for anchored girder is to checkthe bearing capacity and construction quality.The test includes static load test and dynamic load test.
8.0.2 Before the load test of rock wall,the test outline shall be worked out.Its contents include the grade of static and dynamic loads,test method,the layout of observation cross sections and instruments,the alarming and control values of instruments,data records and dataanalysis,etc.
8.0.3 The load test of anchored girder and the load test of bridgecrane shall be carried out simultaneously and the load grades may bedetermined according to the test requirement of the bridge came ordesign requirement.
8.0.4 Before test,the embedded instruments shall be checked toconfirm they are in normal operation condition.
8.0.5 When conducting the load test of anchored girder,reliablecommunication shall be available among the observer commandpersonandtheoperatorofthebridge crane.
8.0.6 During load test of anchored girder,the test shall be stoppedwhen the observation values of the stress meters,displacement metersand multi-point displacement meters reach or exceed the correspondingalarming and control values,and the test Can be continued only afterthe reasons have been ascertained and proper measures have beentaken.
8.0.7 During load test of anchored girder,blasting shall not be.
