新疆玛纳斯县石门子水库诱发地震初步探讨

论述了新疆维吾尔自治区玛纳斯县塔西河石门子水库的地质构造、地层岩性、构造应力场,地震活动背景以及水文地质条件,对水库地震诱震的各种因素与已发生水库地震的实例进行了分析,尤其是对天山地区与石门子水库地质构造要似的努列克和克孜尔水库和诱震诺因素作了讨论,得出的结论是拟建的石门子水库蓄水后诱发地震的可能性是比较小的。     

困难地区水库定桩测量

在水利水电枢纽地区,大坝施工开始以后,要进行水库淹没区水库定桩的测量工作,据以迁移居民和建筑物,清理库底,调查与计算水库淹没所引起的各种赔偿。     

水库及周缘地区诱发地震危险性评定的一种模型及其应用

对已蓄水并建有地震观测台网、毗邻长江三峡水库的湖北清江隔河岩水库及其周缘地区各不同位置的诱震总体组合环境（条件）及相应的诱发地震活动结果进行统计、计算和分析,建立了一种诱发地震危险性评定模型,据此模型对长江三峡水库及其周缘地区的水库诱发地震危险性进行了预测和评价     

东江水库地震活动特征

东江水库自1986年蓄水以来,在库区出现了频繁的地震活动,延续时间已达10年,最大地震为M_L 3.2级.分析认为,这些地震具有国内外一般水库地震的共同特征,属于水库诱发地震,其序列特征属震群型.由于水库坝高、容量大,且库区有活动断层和岩溶发育,诱震机制可能为荷载效应、断层孔隙水压效应和岩溶塌陷.

Diagenetic reactions in reservoir strata and geochemical properties of pore fluid and its origin in Songliao Basin

The reservoirs of the SOngliao Basin are composed of typical unstable sandstones,with high percentages of volcanic fragments and feldspar,In the course of sedimentation and burying,a series of physical and chemical reactions took place between minerals and pore water and water-rock reactions and ion exchange caused changes in ion assemblage of pore water,Hydration-hydrolysis,dissolution and the albitization of feldspar made many ions free from their framework and inter into the pore water,and induced the precipitation of a large amount of authigenic minerals such as smectite and chlorite,During the diagenesis of sandstone.diagenetic reactions involved several stages with increasing depth,and so did the precipitation of authigenic minerals and the transformaiton of minerals.The migration of ions is related with the precipitation,transformation and dissolution of authigenic minerals.Thus,to deepen our study on sandstone diagenesis is an important link for the analysis of ion migration in the evolution of pore water ,the origin and evolution of pore water could be tracked in terms of the geochemistry of fluid inclusions in authigenic minerals.And the isotopic composition of the authigenic mineral calcite can provide its genetic information.     

宿鸭湖水库洼地段坝后渗水的形成机制及治理

宿鸭湖水库是一座综合利用的平原大型水库,经７５．８特大洪水考验后暴露出坝基渗漏及渗透稳定等诸多工程地质问题。本文通过对多次勘察及水库观测资料的整理分析,对洼地段坝后渗水的形成机制进行了论证,指出坝基粉质粘土（Ⅲ）的大孔隙结构与坝后排渗设施不完善、年久失修是该段坝后渗水的主要原因,并提出治理措施,建议被设计部门采纳。大坝经加固除险施工,水库运行１５年来证明,大坝安全,水库运行正常。
