A loading device with the displacement rate control is developed for the model loading tests. Under the condition of displacement rate control, the indoor model loading tests are conducted on the TJ-1 lunar soil simulant by using a foot pad as footing. The average stress of the foot pad bottom is calculated with three different methods. The main conclusions from the analysis of the test results are as follows. The bearing capacity and deformation modulus under the foot pad increase approximately linearly with the loading rate. The bearing capacity calculated using the actual contact area between the bottom of foot pad and the TJ-1 lunar soil simulant is a little larger than that calculated using the maximum section area of the foot pad. The bearing capacity calculated using the maximum section area of the foot pad is recommended for the safety stock. The deformation modulus calculated using the actual contact area under the foot pad loading is between those calculated using the maximum and minimum section areas of the foot pad.
