Unsaturated Expansive Soil

In view of the holes appearing in different area of geo-membrane when the geo-membrane technology is applied to the unsaturated expansive soil slope, the VADOSE/W is used to analyze the wetting-drying cycles caused by rainfall and evaporation on slopes covered by geo-membrane. The influence on the pore-water pressure and volume water content were discussed just caused by the holes. The results show that the hole is nearer to the toe of slope, its impact on the whole seepage field is greater. In addition, the hole appears on the top of slope that the wetting-drying cycle effect is remarkable. It is ensured that the integrity of the geo-membrane which in the lower slope and take some drainage measures in the construction process.

The wetting-drying effect of expansive soils plays an important role in slope stability analysis. According to the depth of atmospheric effect and the field observation data of moisture content, laboratory experiments on the strength of expansive soil with two wetting-drying cycle amplitudes were performed to discuss on the wetting-drying effect of expansive soil. The results show that the shear strength of expansive soil decreases with increasing number of cycles and finally reaches to a constant state. The value and cycle number of the constant state reduce with increase of amplitude of variation of water content. Furthermore, the stability analysis of expansive soil slope is studied with considering the wetting-drying effect. The results may provide the reference for the parameter selection in slope design.

Xiping iron smelting site is the fourth installment of the national key cultural relics protection units. The protective house is surrounded by water, with its base on expansive soil. With the influence of the slide of dams during the flood season, a lot of cracks occur in the protective house and its surrounding, resulting in severe potential danger to iron smelting site. The effect of expansive soil, steep slope reservoir and rainfall on house deformation is analyzed, qualitative and quantitative analysis on slope stability is conducted, results indicates that the protective house will be damaged under rainstorm or continuous precipitation, basic stability will be lose under natural condition.
