Theory and Experimental Results about the Application of Remote Sensing to Earthquake Prediction

In this paper,the theory for applying remote sensing to earthquake prediction has been elucidated and an experiment has been made.Through the experiment,it has been found that the characteristics and temperature of infrared radiant of rocks vary as a function of rock stress,the order of magnitude of radiance variation is 10-5(W/cm2 sr um),the amount of variation of the radiant temperature is 0.2℃~0.8℃ and some significant precursor information has been discovered.The experiment has verified preliminarily that the advanced technology of remote sensing can be applied to earthquake prediction.     

耗能-隔震柔性底层钢管混凝土-钢筋混凝土组合框架的实验研究

本文用钢管混凝土柱作为结构底层耗能柱、用承重墙和隔震器控制结构底层倒塌破坏,从而提出了一种新的耗能-隔震柔性底层结构体系。通过本文12根钢管混凝土柱和文献[7]中7根钢管混凝土柱的低周疲劳实验,初步确定了钢管混凝土柱地震损伤模型的参数;通过两个钢管混凝土-钢筋混凝土三层框架模型和一个纯钢筋混凝土三层框架模型的拟动力实验,研究和比较了两类结构体系的地震损伤。     

皖南东至地区寒武系层序地层研究

皖南东至地区寒武系在地层分区上可以分为下扬子地层分区、过渡地层分区和江南地层分区，生物群上出现了两区特征分子和过渡区的混生现象，并处于台地与盆地交接部位。通过对分别位于台地、斜坡和盆地露头层序地层研究，将寒武纪地层自下而上划分为三个Ⅱ类沉积层序和二个Ⅰ类沉积层序，早寒武世的三个Ⅱ类沉积层序的陆架边缘体系域不发育；中寒武世晚期到晚寒武世的二个Ⅰ类沉积层序皆由低水位体系域、海侵体系域和高水位体系域 组成三元结构。通过层序地层分析和沉积体系演化建立了相应的海平面变化曲线，自早寒武世早期本区海平面达到最高位和最大上升速率后，至寒武纪末研究区海平面总体处于下降过程，即海平面为累进式的缓慢的下降。     

关于推行岩土工程专业体制的思考与实例

岩土工程专业体制的核心内涵,是强调岩土工程勘查,设计,施工,监测,监理５个环节的整体和统一性。岩土工程师,不仅要为建设工程设计提供地质资料,而且还要积极参与或争取主持整个岩土工程项目的设计与施工,本文以实例阐明了其可能性与必要性。     

On the Unconformity between the Triassic and Jurassic in Weiyuan, Szechuan

To the north of the famous Tseliutsing salt district of central Szechuanthere exists a big dome-anticline, which is clearly shown in Tan and Lee's [1]Atlas for "Geology of Szechuan and Sikang." Since this anticline occupies thegreater part of the district of Weiyuan, it may be conveniently termed the     

松辽盆地南部深层地震资料处理方法研究

针对松辽盆地南部深层原始地震记录接收能量弱、信噪比低、各种干扰波严重和地表条件多变等存在严重的静校正问题，尝试利用CGG、Foucs、Grisys、Promax等多套处理系统的优势模块对跨工区二维大吾4面进行深部地层的折射波静校正、反褶积、剩余静校正、DipMoveOut、偏移等关键技术的联合处理方法试验研究，形成了一套针对松辽盆地南部深层地震资料处理的有效方法。     

西藏北部雄梅-曲松波地区早白垩世多尼组及沉积环境探讨

在西藏北部区域地质调查过程中,发现多尼组岩性自西向东有一定的变化。西区(雄梅地区)下段为深灰、灰、浅灰色微、薄层状粉砂质泥岩、粉砂岩、细砂岩韵律层;中段为成熟度略高的细、中、粗粒石英砂岩韵律层;上段为新建立的地层单位达过火山岩,为中性火山岩。东区(曲松波地区)下段以黄绿、灰绿、土黄色中细砂岩为主夹少量粉砂岩及含砾粗砂岩;中段为灰绿、黄绿、紫、灰紫色粉砂岩、细砂岩韵律层;上段为新建立的地层单位弄巴砾岩,为紫色粗砂岩、砂砾岩、砾岩。多尼组呈带状分布于班公错-怒江缝合带与永珠蛇绿岩带之间。在研究区内多尼组以海岸砂堤及海滩沉积环境为主;研究区以西以浅海相沉积环境为主;研究区以东以潮坪泻湖及沼泽沉积环境为主。中特提斯海东部海岸在多尼组早期可能在研究区以东,中期可能曾移至西区,晚期可能移至东区。这一结论确定了多尼组沉积时期中特提斯海海进、海退过程,它为研究中特提斯海的演化历史、古地理轮廊的确定及青藏高原的形成演变历史提供了新的资料。     

Monitoring Glacial Shrinkage Using Remote Sensing and Site-Observation Method on Southern Slope of Kalik Mountain, Eastern Tian Shan, China

Currently, one of the effective means in monitoring glacier change in regional scale is remote sensing and site-observation method. In this article, we present a study of comparing glacier area in 2005 derived from SPOT5 satellite image with area in 1972 derived from topographic maps. Moreover, Miaoergou (庙儿沟) flat-summit glacier is site observed to verify glacial change in regional scale. During the study period, glaciers located in the southern slope of Kalik (喀尔里克) Mountain re-duced their area by 12.3%. ...     

Mantle Branch Structure in the South-Central Segment of the Da Hinggan Mts.,Inner Mongolia and Its Ore-controlling Role

Abstract: Mantle branch structure is the third tectonic unit of multiple evolution of a mantle branch. It is not only the main mechanism of intercontinental orogeny, but also an important ore-forming and ore-control structure. Studies on geotectonic evolution, regional geological characteristics and ore-forming and ore-control structures have shown that since the Mesozoic the Da Hinggan Mts. region has entered a typical intercontinental orogenic stage, and it is closely related to mantle branch activities. The south-central segment of the Da Hinggan Mts. is a typical mantle branch structure and possesses obvious magmatic-metamorphic complexes in the core, detachment slip beds in the periphery and overlapped fault depression basins. Moreover, all of these are the principal factors leading to ore formation and ore control in the region. This paper also further explores the mechanism of mineralization in the south-central segment of the Da Hinggan, summaries the rules of mineralization, puts forward the models of mineralization and points out future ore-exploring orientation.
