The invention belongs to the field of engineering geology and geotechnical engineering, and particularly discloses a method for testing the in-situ deformation modulus of a strongly-weathered and strongly-unloaded rock mass at the superficial part of a rock slope, which can be used for testing the in-situ deformation modulus of the strongly-weathered and strongly-unloaded rock mass at the superficial part of the rock slope under the conditions that the morphology of the slope is not disturbed and damaged, the slope is not excavated and the completely-weathered and unloaded rock mass is completely retained. Carrying out large-scale deformation modulus testing on the rock mass of a strong weathering and strong unloading zone at the superficial part of the rock slope in situ so as to obtain related rock mass mechanical parameters; the method comprises the following steps: selecting a test site, reinforcing the test site, pouring a test bearing plate, drilling a counter-force device mounting hole and a wave veloc
