The utility model provides a rock stock up -pull testing arrangement, the device includes: first supporting mechanism, loading device and coupling mechanism, wherein, loading device installs in first supporting mechanism, and loading device is connected with coupling mechanism, and the equal position of each stock is connected with coupling mechanism adjustablely, and loading device is used for applying uplift force to each stock. The utility model discloses need not to change coupling mechanism, can realize carrying out the up -pull experiment to a plurality of stocks that are in different positions, carry out the up -pull experiment to a plurality of stocks that are in different intervals promptly, can carry out accurate location to the relative position between each stock better, improved test data's accuracy to convenient to use, in addition, this rock stock up -pull testing arrangement not only is applicable to the naked place of basement rock, and the top that is particularly useful for the basement rock layer covers the place that there is the soil layer, can simulate the actual operational environment of stock better, and total resistance to plucking bearing capacity of the stock ensureing to test out is more accurate.
