Scattering of seismic waves by cracks in multi-layered geological regions: II. Numerical results

The mechanical model for plane strain, time-harmonic seismic wave propagation problems in cracked, multi-layered geological regions with surface topography and non-parallel interfaces was described in the first part of this work. Here, this model is used to investigate the response of such a region to the presence of traveling elastic waves generated by a seismic source. The computational methodology that was developed in the first part is based on a combination of both the regular (displacement-based) and the hypersingular (traction-based) Boundary Integral Equation Method (BIEM). First, the accuracy and convergence characteristics of this hybrid BIEM are studied. Then, a series of problems involving four different configurations of a reference geological deposit with both interface and internal cracks are solved, for a loading that is due to a seismically-induced pressure wave propagating upwards from the underlying rigid half-plane. The purpose of the numerical study is to investigate the influence of various key parameters of the problem, such as frequency and incidence angle of the incoming wave, size of the surface relief, location and size of the buried cracks, interaction effects between cracks and finally the presence of layers, on both the scattered displacement field and the stress concentration field.     

Investigation of a landslide in the new site of Badong County by integrated geophysical survey

An integrated geophysical survey which combines vertical seismic profile method, shallow reflection seismic method, electric sounding, soil temperature measurement and radioactive gas measurement was used to investigate Zhaoshuling landslide in the new site of Badong County and to assess the stability of the landslide. By rational use of these methods together with borehole geological profile and other geological information, the spatial distribution of the landslide body, the formations and structures within and without the landslide body were determined and the stability of the landslide was also assessed, thus making great contribution to the successful and rational investigation and assessment of the landslide.     

北祁连石居里地区Cu(Zn)-S矿床地质特征及综合成矿模式

文章主要论述了北祁连山西段石居里矿田内Ⅵ号沟、Ⅷ号沟、九个泉等矿床的基本地质特征，并与北祁连山东段老虎山地区银硐沟、猪嘴哑吧等矿床对比。结合其早古生代构造演化历史、古洋脊或弧间、弧后拉张环境确定矿床类型，将上述3个矿床归属为蛇绿岩Cu(Zn）－S型矿床（类塞浦路斯型）。建立综合成矿模式的基本要求：（1）矿床具有一定的时控性，有一定的含矿层位；（2）生长性断裂的积极参与；（3）海底火山喷发、喷气中心与次级盆地双向控制；（4）多元热流体成矿系统。

视距测量方法的改进

在视距测量中．本文应用上、下视距丝与中丝所夹视角均为17′11″这一原理，证得：上、中、下三丝读数与坚盘读数之间存在着一个多余观测；去除中丝读数同样能求得测站点与碎部点间的平距及高差，且不影响结果的精确性。碎部测量时，对每个碎部点就从根本上减少了一个观测要素。实践证实：此法可节省约15％的碎部测量时间.     

Modeling,ray tracing,and block nonlinear travel-time inversion in 3D

We describe an integrated forward and inverse three-dimensional modeling system that can deal with complex geological structures. The system has been designed to handle large-scale problems by using a distributed approach. It uses seismic ray tracing for forward simulation, time-to-depth mapping, and nonlinear travel-time inversion.A novel decomposition method is our tool to attack large-scale problems in a parallel approach. The system is fully implemented and we demonstrate its performance with synthetic examples.This research was partially supported by the National Science Foundation under SBIR Grant III-9300992.
