ABSTRACT:
A method of insitu testing of soil compressibility comprises boring a hole in the soil to be tested, reconstituting the lateral stress environment in the soil adjacent the bottom of the borehole and then performing vertical compression tests directly on the undisturbed material at the bottom of the borehole. The testing apparatus of the invention includes a cylindrical container adapted to be pushed to the bottom of the borehole. An inflatable circumferential membrane around the exterior periphery of the container is inflated to reconstitute the lateral stress environment. The load may be applied to the base of the borehole by either a closed or inflatable fluid cell or directly by a flat or stepped load plate.
In one embodiment of the invention, a thin-walled cylindrical tube penetrates the soil at the base of the borehole so as to laterally support the test soil for substantially one-dimensional vertical compression testing.
