On the base of analysis concerning Tianjing and Tanggo-Xingang soil properties and observation results of settlements, some rules of settlement of buildings in the area were obtained. Final settlements, settlements at end of construction and the time of final settlement were discussed. Tests used for determining paramcters of four models were introduced. The parameters in Duncan-Chang model are determined from isotropic consolidation test and the parameters in Gong-Xiannan model from Ko consolidation tests while the parameters in the model proposedin chapter 2 from the equal increment stress ratio test and ones in the bounding surface model developed in chapter 3 from the effective stress-path of CIU test.

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.

In this thesis, we find that dlg is indispensible in the establishment of anterior-posterior and dorsal-ventral polarity of drosophila oocyte. Removal of Dlg function from the posterior follicle cells using the FLP/FRT system leads to disruption of oocyte skeleton reconstruction that is elicited by the failure of those posterior cells to differentiate normally in mid-oogenesis. We demonstrate that abnormity of Notch, JAK-STAT and EGFR signal pathway in dlg mutants contributes to this aberrant differentiation. dlg null mutant also blocks the normal differentiation of two groups of anterior follicle cell-stretched cell and centripetal cell, but not border cell, with a lower penetrance. However unlike the result in posterior follicle cells, Notch and JAK-STAT signaling are both undisrupted in all mutant anterior follicle cells, implying other fate determinants may be involved.
我们的研究发现,后端滤泡细胞中的Dlg在果蝇卵子发生中期卵母细胞前后轴和背腹轴建立过程中也是必须的,PFC中dlg完全缺失型突变引起PFC的分化异常,导致卵子发生中期卵母细胞骨架重组异常,Stau、Grk等极性决定蛋白定位错误。dlg突变阻碍了Notch、JAK-STAT、EGFR等调节PFC分化的信号通路的激活。dlg突变的PFC也没有获得前端滤泡细胞命运。dlg突变不影响前端滤泡细胞群中边界细胞的分化,但是在一定程度上影响伸展细胞和向心细胞的分化,并且这种影响不依赖于前端滤泡细胞Notch或JAK-STAT信号激活的异常。
