Require two times of the limit working load of single limb and split limb. Test method: the test load shall be increased one by one, and lifted to the height of100 200mm above the ground, and the suspension time shall not be less than lOmin；; Visual inspection shall be carried out after unloading. Repeat the test for three times. If there is no crack or permanent deformation in the structure and no abnormal looseness or damage in the joint, it is considered that the static load test is qualified.
Extended data:
According to the test objects, it can be divided into shallow plate load test, deep plate load test, composite foundation load test, rock foundation load test, pile (pier) foundation load test and anchor (pile) test. According to the loading mode, it can be divided into vertical compressive test, vertical pull-out test and horizontal load test.
Test equipment: Jack? Load sensor? Displacement sensor? dial gauge
Static load test should be adopted for the composite foundation formed by foundation with Grade A design grade or complex geological conditions and low reliability of pile quality.
