华北石炭——二叠纪煤系粘土岩夹矸中铝的氢氧化物矿物研究

华北石炭——二叠纪煤系太原组和山西组不同煤层粘土岩夹矸中,广泛含有一水软铝石、一水硬铝石和三水铝石。大多数一水铝石矿物呈薄纹层状、似层状及层状聚集于富岩质及富有有机质粘土岩夹矸条带中,有的呈细脉状沿炭质条带及粘土岩夹矸层理的节理裂隙分布,并与玉髓、方解石、高岭石或迪开石和铵云母细脉共生。铝的氢氧化物矿物可以作为成岩古温度和成岩阶段划分的标志矿物。最后还讨论了该矿物的成因。

随机地震荷载作用下饱和粉土的液化特性

为了考虑随机地震荷载作用下饱和粉土的液化特性，研究了如何通过合理的地震响应分析确定饱和粉土层受到的随机地震荷载，进一步探讨了随机地震荷载作用下的动三轴试验技术，以及利用此种试验分析饱和粉土液化特性的方法。研究结果为形成判别饱和粉土层地震液化可能性的新方法提供了依据。

Radon,Lung Cancer Risk and Environmental Geology in Gejiu Area

The incidence of lung cancer in the Gejiu area of Yunnan Province ranks the first in the world.The radon level(indoor,soil) was measured in the Gejiu area by the SSNTD method from 1990 to 1996,The result indicates an extensive high-level of indoor radon in that area though U and Th are lower in local limestones,The indoor radon level of houses located in the geologic fault zone is 6 times high that 2km far from the fault zone.The reason probably is that the radon level of soil in the fault is 6-8 times high that 1 km far from the faults.our data indicate that a lower range of radon levels,0-100Bq.m^-3,exists in healthy families.However,a higher radon level,over 800 Bq.m^-3,is often found corresponding to that of cancer patients‘ homes(the house-owners are suffering from either lung cancer or leukaemia or liver cancer),Obviously,an increase in lung cancer incidence follows an increase in indoor radon level,The risk of cancer induced by indoor radon is no longer an inference,but a fact.     

Site effects at a vertical accelerometer array near Paducah, Kentucky

The downhole vertical accelerometer array VSAP near Paducah, KY, consists of three-component accelerometers at the surface, the top of the McNairy Formation (−41 m), and the top of the Paleozoic bedrock (—99 m). The array is at the northern end of the Mississippi Embayment, and it was installed to verify the ground-motion modeling for the site, assuming a significant earthquake in the New Madrid Seismic Zone. Accelerograms from 4.2 and 2.0 m_b earthquakes were used to check aspects of the modeling pertaining to linear behavior of the soil column, and to review the soil column models derived by drilling and geotechnical methods and through the use of high-resolution P- and SH-wave seismic refraction in reflection techniques. Results of the study indicate that for the linear case the soil column models derived by the two techniques are equivalent, and that the most important boundary in the soil column, with respect to amplification of the ground motions, is the interface between the limestone bedrock and soil.     

512铀矿床地浸条件及技术经济评价

本文应用铀矿普查及地浸试验中获取的资料，对５１２矿床地质构造、矿石物质成份、矿床水文地质、工程地质及自然经济地理等地浸条件及矿床技术经济条件进行了分析评价，认为５１２矿床地浸条件较好，地浸技术指标适中，用酸法地浸开采具有耗酸量少、成本低、经济效益好的特点。在今后的开采中，若能解决伴生元素Ｒｅ，Ｓｅ，Ｍｏ的综合利用问题，将会大大提高矿床的经济价值。     

基于三对象多维标度法及其应用

本文提供了基于三对象（样品或变量）的多维标度法。计算方案是通过一维标度求法（数量化理论Ⅳ的扩展）和多维标度求法把原始问题降至为标准特征值—特征向量问题来解决，该方法的主要目的是提取更多信息、简化数据结构并重新标度研究对象于新的低维空间，以便能通过二维“因子轴”来直接检验，它适合于定性和定量数据。编写计算程序进行标度分析，在内蒙古赤峰某金矿进行矿产预测应用效果良好。     

岩溶地下水集中开采区水质系统预测研究

在岩溶地区，地下水的超强度开采与工业“三废”及生活废弃物不合理的排放，造成了地下水较严重的污染。用动态系统方法建立的地下水污染时间序列递推预测模型，在岩溶地下水环境质量预测与管理方面都具有指导意义。     

松江河电厂小山水电站导流洞出口边坡稳定性分析

小山水电站导流洞出口边坡其地质结构为下部中侏罗世安山岩（αＪ２），其上覆盖了第三纪末第四纪初的玄武岩（βＮ～Ｑ），两者间为不整合接触，不整合面夹有０．１～０．６ｍ厚的粘土状及碎石粘土状夹层，产状倾向河床，倾角±２５°。在上覆玄武岩层中见有高倾角的宽张裂隙带，与不整合面一起构成松动岩体，不整合面为底滑面。通过边界条件的分析和稳定计算，松动岩体的抗滑系数Ｋ＝３．１０２，边坡是稳定的。在施工过程中采取了相应的安全保护措施，导流洞出口提前２８ｍ进洞，节约挖方量６００００ｍ３，提前了工期。经三年多的施工到运行，边坡无异常变化，表明该项优化设计是可行的。
