云南地区房屋建筑的震害矩阵

自1992年4月23日云南孟连西中缅交界6.7、6.9级地震始,地震部门对云南地区的破坏性地震进行了现场灾害调查和经济损失评估。1992~2003年,云南地区共发生50次破坏性地震,积累了丰富的震害资料。本文根据云南地区的主要建筑结构,统计分析了50次地震不同烈度区的破坏比、损失比和震害指数,给出了房屋建筑的震害矩阵。     

三峡库区塌岸预测新方法——岸坡结构法

水库塌岸是三峡库区重大地质灾害之一。通过三峡库区数百段库岸的塌岸地质现场调查和预测分析的基础上,提出了类似三峡这种山区河道型水库的塌岸预测新方法——岸坡结构法(RBSM),并给出了详细的图解方法和预测步骤。同时,开展了二滩、宝珠寺和龚咀三个运行中的类比水库和三峡水库(139m蓄水)的塌岸预测检验,验证结果表明该方法适宜于三峡水库以及类似的山区河道型水库塌岸预测,从而为水库塌岸预测与防治工程提供重要依据。     

腾冲盆地阻水构造的发现

腾冲来凤山北麓前缘,潜伏一段阻水构造——地下水位坡降带。从研究13个水文钻井、119口民间井、2个泉水露头地下水位特征入手,采用古水文和现代水文地质研究方法,论证此段阻水构造的存在。     

云南茶树林铅锌矿电磁波找矿效果

茶树林铅锌矿，过去认为震旦系赋矿，钻探验证未见矿。本次利用物探方法实施深部探矿。依据物探异常，结合地质规律综合分析，认为是构造控矿。布置验证坑道，沿断裂破碎带发现新的厚大、品位高铅锌矿体，收到良好的找矿效果。     

一种扩展的基于结构检测的最优多视极化SAR相干斑滤波算法

全极化数据的可得,使得利用极化散射矩阵以减少多视全极化SAR图像中的相干斑成为了可能。其中,被称为最优的多视极化白化滤波器（MPWF）就是一个典型例子。然而,为提高滤波器参数估计的精度,同时能够自适应的检测图像中的结构特征,在滤波时采用适当的窗算法是必要的。本文提出了两个有效的窗算法,并用1994年NASA SIR-C/X-SAR,L band,经过四视处理的天山森林的极化数据进行了仿真。实验结果表明,这两种算法不仅很好的达到了降噪效果,而且对图像的纹理信息以及结构特征（即边缘特征、线性特征、强散射体特征）的保持效果是最佳的。

地震折射波法探测研究张强地区的构造特征

张强地区位于中朝地台北缘的吉黑地槽区,其基底岩系和构造特征与中朝地台的基底和构造特征有明显的差别,通过２００ｋｍ的折射波法探测,得出如下结论：（１）本区基底构造线方向呈现近ＳＮ或ＮＮＷ向,二条此方向的断层划分出三个构造单元。（２）该区内中生代前基底分为两套地层,其岩性、断层特征和基底埋深均有差别。     

Pit crater structure and processes governing persistent activity at Masaya Volcano, Nicaragua

 Persistent activity at Masaya Volcano, Nicaragua, is characterised by cycles of intense degassing, lava lake development and pit crater formation. It provides a useful site to study the processes which govern such activity, because of its easy accessibility and relatively short cycles (years to decades). An understanding of the present activity is important because Masaya is visited by large numbers of tourists, is located close to major cities and has produced voluminous lavas, plinian eruptions and ignimbrites in the recent past. We provide structural and geophysical data that characterise the "normal" present state of activity. These indicate that the ongoing degassing phase (1993 to present) was not caused by fresh magma intrusion. It was associated with shallow density changes within the active Santiago pit crater. The activity appears to be associated predominantly with shallow changes in the pit crater structure. More hazardous activity will occur only if there are significant departures from the present gravity, deformation and seismic signatures. Received: 16 May 1997 / Accepted: 29 October 1997     

Measuring the maritime economy: Spain in the European Atlantic Arc

Despite the importance of the socio-economic dimension of the use of marine waters, there has been little research in the field until recently, when interest has grown in the concept of ‘blue growth'. This paper aims to contribute to filling this gap with a socio-economic assessment of the main maritime sectors, focused on the Spanish part of the European Atlantic Arc. To this end, it first proposes a theoretical structure for the maritime economy and then collects and classifies comparable and reliable maritime socio-economic indicators. The data obtained allows us to assess the size of the Spanish maritime sector and the position of the Spanish Maritime Cluster in the wider context of the maritime economy of the European Atlantic, as well as discuss the appropriateness of a strategy of forming clusters at the national level vs. a transnational approach. The results indicate differences between regions in the European Atlantic Arc that complicate the development of integrated policies to stimulate blue growth. Extending our knowledge of the maritime economy of the European Atlantic Arc will make it possible to design strategies that address the real issues, increasing the likelihood of these being effective.     

东营凹陷八面河北部斜坡带构造特征及形成机制

研究了东营凹陷八面河北部斜坡带的断裂特征、构造演化特征及其形成机制,明确了该区的断裂展布特点和断层活动性,弄清了北部斜坡带的演化规律,同时分析该区的构造变形特征。结果表明：中生代以后,八面河地区存在2种独立的构造变形系统：一是板块边缘相互作用力;二是到后期由于板块的持续俯冲,地幔底辟作用在岩石圈底面产生的牵引力。八面河北部地区在这2种构造力的综合作用下,不同时期表现出不同的构造变形特征。
