- Description
- One approach to mitigate the effects of expansive soil foundation movements on light structures, is to rip the soil foundation prior to the construction of a slab-on-ground, supported on deep piles. This study evaluates the potential for “ripped” soil to swell or collapse beneath a foundation slab, cast on a ripped soil foundation. A series of tests are described in which a series of different expansive clay soils are prepared to different clod sizes and different initial water contents, prior to being placed in containers of various scales, surcharged with a nominal pressure of 9 kPa and wetted. The results show that the soil response may include swelling, collapse or both, depending upon the soil type, the initial water content, the ripped soil texture and the method of wetting used. The practical limitation of this type of experimental research are discussed in detail.
