With the rapid development of the engineering actions in the highland with particular stratigraphic sequence, because of the buildings at the back of the sliding body and the cutting slope at the front, the pushing force of rock and soil in slope increased, but the anti-sliding force weakened. On the other hand, during the rainfall surface water immerged into the layer interface of the diatomite along the unloading cranny, resulting in the diatomite becoming soft after absorbing water and its shear strength lowered. At the time, the water level went up, the dynamic water pressure and uplift pressure increased, the anti-sliding force continued to reduce. Therewithal, the landslides occurred along sliding surfaces with small tilt angle.

在丘陵区此独特的层序地层近年来随着人类工程活动强度的增大，滑体后缘建筑，前缘切坡，造成下滑力增加，抗滑力减弱；另一方面在降雨的作用下，地表水体沿着卸荷裂隙通道浸入到下伏硅藻土层界面，硅藻土吸水软化，抗剪强度减弱，同时地下水水位上升，动水压力和扬压力加大，抗滑力进一步降低，于是产生了低倾角滑面滑坡。

In this paper the viscous flows around a mathematical SWATH in full scale are simulated based on the computational fluid dynamics commercial software FLUENT. The numerical results of total pressure, wall shear stress and the corresponding viscous resistance coefficient at different velocity are obtained. The computational viscous resistance coefficients are compared with the estimated ones using empirical formula. The validity of the software to predict the three dimensional viscous flows and viscous resi...

How to ensure this new structure to be in elastic state under frequent earthqu ake, be mendable under design earthquake and not collapse under infrequent earthquake, especially the last item, is the problem to be solved imminently in engineering field. Center around this problem, 5 aspects of investigation are carried out as following:(1) The experiment of seismic performance of ASCCs in this new frame structure has not been reported, in order to study this problem, 9 ASCC specimens with shear steel plate are tested subjected to the horizontal low cyclic loading, in which, the shear span ratio is 3 and axial compression ratio is different. The hysteretic curves of 9 specimens are obtained. The seismic performance indexes such as energy dissipation, stiffness degradation, strength degradation, skeleton curves and ductility of this kind of column are acquired, and the seismic fortification measures including ultimate values of axial compression ratio under different seismic degree are suggested.
