The results show that the hydraulic fracturing pressure is intimately related with tensile strength and tridimensional stress state of the soil. With the increase of tensile strength and minor principal stress, the fracturing pressure is enhanced.

Those rarely refer to the researches about water pressure function mechanism. In fact, the water flow intrudes upwards with a loss of the distance water and energy wastes for splitting rocks when confined groundwater intrudes upwards through coal seam water-resisting layer. The water flow under the coal seam scaleboard consumes more energy after it intrudes at a certain height.

Before fissuration, osmotic adjustment occurred by the addition of solute to cells and decreasing the loss of water in the body, so that it could maintain normal turgor pressure during drought. After fissurate growth, turgor pressure was maintained by higher cell and tissue elasticity lower ε(superscript max and by osmotic adjustment for normal plant development in dry conditions and to avoid dehydration under water stress during the drought period, but it also became more sensitive to water stress. The ability to maintain turgor pressure varied from strong to weak during the period before, during and after fissuration. Fissurate growth decreased the ability of P. mongolica to maintain turgor pressure and led to changes in walls related to drought tolerance.

It is an ancient species in its own genus and well-adapted to drought environments with fissurate growth and summer dormancy. Methods We selected Dengkou as our research site and collected three stages of P. mongolica (before, during and after fissuration) during August 1-5, 2002 and 2003. We used PV technique and measured several water relations parameters (φ,φ, ROWC, RWC,△(subscript φ),ε etc. in different stages of fissurate growth for comparison and analysis of drought tolerance and its mechanisms. Important findings Different stages of P. mongolica had different abilities and pathways to maintain turgor pressure. Fissurate growth decreased the species' drought tolerance and involved multiple adaptations to drought.

The endogenous phytohormones of fissurate growth species-Reaumuria trigyna Maxim, Reaumuria soongorical Maxim and unfissurate growth species-Helianthemum soongoricum Schrenk living in the same place was studied.The contents of IAA, ZR are higher in the fissurate place of Reaumuria trigyna Maxim; The contents of GA3, ZR are higher in the fissurate place in Reaumuria soongorical but the content of endogenous phytohormones are higher in seedling of Helianthemum soongoricum Schrenk ,which illuminates endogenous phytohormones are higher in the actively growing parts and probably adjust the fissurate growth.

The results show that, using the cement as a filler, there are no impacts on the high temperature performance, neither do the marshell stability and the split strength; nor the residual stability and the TRS are highly improved, even exceed the original mixture, which explains that using the cement as a filler also is used for the asphalt mixture with PR.
