Aiming at researching on stability of slope affected by precipitation intensity, transient saturated-unsaturated seepage finite element method and slope stability finite element method are combined in this paper. Vadose field of slope is simulated in different precipitation intensity. Based on vadose field, the writers analyzed the stability of slope affected by precipitation intensity. The research results indicate that water is brought together in the interface first. Then the water level moves toward up and down respectively from the both sides of the interface. On the basis of saturated-unsaturated seepage theory, precipitation intensity has little effect on the slope stability in the first 6 hours after precipitation. After that, slope safety coefficient is relatively high when precipitation intensity is smaller, and vice versa.

Based on unsaturated soil seepage and shear strength theory , to explore the pore pressure dissipation law , it has been analyzed seepage about slope of deep foundation pit in Xian , supporting by pile-anchor retaining structure under the condition of continuous rainy by MIDAS software . The simulation result shows a temporary saturated region would appear on the surface of slope in continuous rainy days , then soil water content increasing as the rainwater infiltrate into a deeper soil layer gradually .For the sake of different cohesion of different time , Combine moisture filed , coming from pore pressure field , with the functional relationship between water content and cohesion , of simulated with filed test dates .The influence law of continuous rainy is derived from stability analysis by strength reduction fem about slope safety factor and stress of retaining structure .

Emotion plays an important role in the human perception and decision-making process. Human comprehension and perception of images is subjective, and not merely rely on lower-level visual features. Semantic gap is regarded as the most important challenge of image retrieval. In this paper, we analyzed the emotional features as well as emotional semantic description of images, which comes from the image emotional semantics retrieval framework. And also the mapping ways and means were summarized from image visual features to emotional semantics. Finally, the disadvantages of emotional semantic mapping and developing tendency were discussed.

Relying on the background of large section soil tunnel engineering, the numerical simulation on three excavation methods for soil tunnel including bench method, arch heading method and cross diaphragm were carried out. Results show that the arch heading method is confirmed as optimum for this project by comparative analysis. And then, according to the monitoring results of the arch heading method, stress development laws and deformation characteristics of surrounding rock and supporting structure of large section soil tunnel were obtained, which include regression analysis functions of the development trend of vault settlement and horizontal convergence, distribution characteristics of ground surface settlement, development law of primary support stress and contact stress between surrounding rock and support, influence scope of tunnel face excavation and corresponding deformation law of surrounding rock as well as main deformation stage. Besides, the reliability of simulated results is verified by comparing them with the monitoring measurement data.

The bearing capacity of residue pile composite foundation formed by deep dynamic compaction, shorted for DDC, is calculated and analyzed by ANSYS finite element software. The analysis results show that pile body and soil between piles have a good coordination, residue pile composite foundation is semi-flexible and semi-rigid and the effect of consolidating foundation is obvious. The purpose of foundation treatment should be taken into consideration primarily to provide reference for future similar projects.
