    HYGROTHERMAL CHARACTERISTICS OF RED CLAY SLOPE UNDER ATMOSPHERIC ENVIRONMENT

    • Many scholars at home and abroad field tests considering regional special soil slope effect of atmospheric environment, especially to the expansion of field tests on soil slope more deeply, and the study on the red clay slope is relatively small. In China, the red clay is widely distributed and its engineering properties are complex. The engineering problems related to the red clay slope are often encountered on the project. If the red clay slope is neglected, it is easy to cause the engineering disaster. Therefore, the establishment of the in situ monitoring system of red clay slope in Guilin city of Guangxi Yanshan area, set up a small weather station, the measurement system of soil moisture and buried TDR thermistor temperature sensor, tracking test the evolution of red clay slope soil water content and soil temperature with climate change, to provide a reference for the follow-up related to the verification model scholars. The monitoring results show that the net radiation and atmospheric temperature are the main factors affecting the slope soil temperature change of red clay, soil temperature change may indirectly reflect the changes of soil moisture content; temperature range of slope of red clay, toe temperature minimum; change slope soil water content are the main factors influencing the red clay slope the stability of the temperature changes play a role in promoting, the coupling effect of temperature and humidity of the two eventually lead to the instability of slope.
