In the explore in water seepage mechanism of highway engineering, at the foundation of author's and other people's research, the author study the groundwater seepage and infiltration of rain and water with the groundwater dynamics, the rock mechanics ,the soil mechanics, the hydrologic geology, the engineering geology, the agrology. With the research result of the water seepage mechanism of highway, the author also study the principle design of waterproof, drainage and water environmental protection. The author's work is as follows:(1) The water circulation, the groundwater type and conversion, the equilibrium and circulation in soil water are introduced and studied; The seepage characteristics of rock and soil in response to stress are analyzed and studied.

The results showed that extremely cold rain and snow weather of Sichuan Basin was related well to the variations of water vapor国产在线无码制服丝袜无码知名国产、 frontogenetic function of Yangtze River Basin. at the mid-lower level of the troposphere, especially at 700 hPa level, there was water vapor convergence exiting lastly in Sichuan Basin for long time. And the time of convergence of water vapor was congruous with of cold air in Sichuan basin, and provided the water vapor conditions for the occurrence of low-temperature disaster.

In the Mu Us desert, either vertical distributions of soil moisture isogram before irrigation or vertical distributions of soil moisture isogram after irrigation shows obviously vertical-layered character. When the irrigation is finished 24 hours later, there is little correlation between vertical distributions of soil moisture isogram before irrigation and vertical distributions of soil moisture isogram after irrigation. All of probability distribution of soil water content before irrigation are left-skewed distribution, but some of probability distribution of soil water content after irrigation is left-skewed distribution, some is right-skewed distribution or normal distribution. The distributed pattern shows different between the probability distribution of water depth of rain gauge and that of soil moisture in horizontal section of different depth. There is close correlation between the distribution of water depth of rain gauge and that of soil moisture in horizontal section, but the correlation debases as the horizontal section turns deeper. Also after irrigation close correlation occurs between the distribution of soil moisture of layers bordering upon each other, but which reduces with space of different layers being larger.

Integrated analysis of 7 times heavy rain in Yunnan from July 19 to August 2 based on actual observation weather datum and satellite cloud atlas and Doppler radar image. The results show that: high-low southwest jet stream is important effect system. The maintenance of southwest jet stream provides water vapor, momentum, fast transfer of unstable energy for the lasting heavy rain. The further configuration of plateau shear line and southwest jet stream is necessarily condition about 7 times heavy rain. The lasting heavy rain appeared on big value region of 500hPa vapour flux and vapour flux divergence. The shear cloud band and subtropical high cloud band crossed and confluenced in Yunnan on the satellite cloud atlas. The maintenance and intensification of shear cloud hand and periphery cloud band of subtropical high correspond quite well to heavy rain falling region and cloud band distribution.
