Finally, we present an arithmetic of multiplehypocentral, heterogenous dislocation, and a multirupture segment superposition model for simulating the earthquake deformation field. The simulated LOS interferometry map presents the distribution characteristics of the earthquake deformation field better than that of previous studied. Meanwhile, a suit of fault geometric parameters of the earthquake is also obtained by the study. Having a better effect upon simulating asymmetry, great dislocation, macro rupture field, and nonhomogeneity of dislocation than the traditional model, the multisegment method is a progress of this work. It provides a better explanation for the study on hypocentral parameters.
基于上述原因,本文对Okada线弹性位错模型的算法进行了改进,提出了&多震源、非均一位错分量、多破裂段叠加&的线弹性模型,该模型模拟出的形变场干涉纹图较好地体现了地震形变场的分布特征,并由此获得了一套较为完整的地震发震断层的几何学特征参数,为破裂带长度、破裂面方向、破裂面大小等震源破裂特征参数研究提供了较好的解释。

Aimed at the complexity of fluvial strata, such measures as well cyclical comparison, step control and geological analysis of reference beds have been applied. Moreover the paper has developed a set of methods the techniques to extract the parameters controlling the formation of intra-sandbody thin interbeds. The present study has examined how thin interbeds affect the frame property and heterogeneity of individual sandbodies; revealed the permeability space distribution mode of meandering distributary channel's single side lithosomic body and straight distributary channel's aggrading lithosomic body. Through applying the distributary channel sandbody structural unit classifying and identifying method achievement, some horizontal wells have been deployed to dig the residual oil in the top of hick pay zone in the xing8-9 area, which shows better effect after they have been put into production.

Wheel/rail noise of the high-speed slab track on concrete bridge and that of the urban elevated supporting block track are predicted respectively. Noise of the slab track, compared with that of the ballasted track, is more severe. The noise of the slab track is about 6.2dBA higher than that of the ballasted track for the receiver nearby the rail, and about 3.5dBA higher than that of ballast track for the receiver
