在地球上广泛分布着像阿巴拉契亚盆岭省那样的褶皱一冲断层带,其形成年代为早元古代.本文列举了许多具有启发性的与第一部分所描述的"典型"实例所不同的变体.波状模式具有普遍性,在褶皱轴迹凸出段和凹进段,其走向弯曲可超过90°.褶皱轴迹凸出段的强烈弯曲似乎与克拉通构造凹人处的断层裂谷或拗拉槽有关.凹进段的强烈弯曲似乎与尖锐的克拉通岬角有关.与这些带有关的地层层序完全不同.绝大部分的上部地层层序包括源于造山带更内部的厚层状三角洲杂岩或其他碎屑楔,其下部变化较大,碎屑岩通常来源于克拉通边部.一些地层层序明显为大的厚层状浅海相碳酸盐岩,另一些主要为碎屑岩、火山碎屑岩或者包括一个薄层的非补偿性层序;而其他则为过渡性的.虽然沿着一些古老造山带绝大部分或所有边缘,缺失褶皱-冲断层带,但在挪威南部奥斯陆地堑中所保存下来的褶皱-冲断层带碎块表明其缺失仅仅是由于侵蚀较深,而使整个褶皱-冲断层带被剥蚀,暴露出其下部的原状基底.

Filler and binder make up a small proportion of bituminous mixtures, hence they are considered as important ingredients of mixtures. Sometimes due to equipment error during production, some mixtures retain extra or a reduced amount of filler or binder as compared to the design mix formula. It is thought that the poor performance of bituminous mixtures is a result of inadequate proportioning of materials and the use of inappropriate compaction tools. This study was intended to appreciate the influence of contents of filler and binder in relation to durability in asphalt mixtures. Filler used was crushed stone passing 0.075 mm sieve, while the binder was 35/50 penetration grade. Several trial mixes were prepared following Ugandan specifications for Road and Bridge Works, and the Asphalt Institute in MS-2. Marshall design method was used, studying volumetric properties with an average stability value of 22.3 kN, average flow value of 3.7 mm, VA of 4.4%, VFB of 69.3%, and VMA of 14.2%. Also, compaction of mixtures to assess its performance at optimum filler and binder contents was done. Compaction was done using an Automatic Impact Hammer, a Vibrating Hammer, and a Superpave Gyratory compactor aimed at simulating secondary compaction by traffic and assessing the retained air voids which was 3.3%, 1.3%, and 0.7% respectively. Generally, in bituminous mixtures when a vibrating hammer or a gyratory compactor is recommended for compaction, coarser mixes would be the best choice.

中国政府层面自上而下的防震减灾管理卓有成效;但是,对于提升全社会的整体防震减灾能力而言,尚需推动基于此而又有民众与基层自下而上广泛参与的全社会治理模式。为发展这种模式积累经验,渭南市地震情景构建示范项目借助参与式行动研究范式,特别关注了中国防震减灾工作当前存在的以下2点广泛不足:一是社会民众与基层的自下而上办法薄弱,且与政府层面自上而下对策之间的相互衔接与促进不足;二是科学研究向实际减灾对策的转化不足,特别是针对自下而上办法的科学研究与应用转化不足。取得的主要进展有:1)基于广泛参与理念,通过"研究者"和"减灾实践者"、"相关者"、"当事人"2方面人员间的密切合作,共同诊断评估了渭南面临的主要地震灾害风险及隐患、共同提炼了针对性的减灾对策改进建议等,从而使情景构建所得的结果或认识更加可靠、所提对策建议更加符合当地实际需要;借助行动研究过程平台,尝试了风险评估、风险沟通和风险对策改进3大环节的无缝衔接与同步互动,促进了科学研究与实际应用的直接对接与就地转化。2)基于多尺度、多层面视角和同时为"政府"或"部门"与"基层"或"民众"两大类用户服务。在关注改进自上而下对策的同时,针对薄弱的自下而上办法,特别是就这两大对策途径间最广泛与最可持续的接口——宣传教育和家庭、学校、社区减灾,开展了大规模的专项调查分析,梳理了系列化的现今本底与改进方向。3)聚焦改善减灾宣教和促进风险沟通,编创了由"故事"引导的2版内容与形式均有显著差别的地震情景叙事读本:政府版和公众版,以期借助"故事"和艺术呈现"故事"带动人们更好地理解与应用情景构建结果和认识,借助"故事"演绎社会性灾害脆弱成分——"留守儿童家庭与贫困"之于灾害的强化与叠加效应,促进人们对地震灾害风险更加全面与深入的认识;在理性刻板科学中融入感性与人文艺术情怀,以引导共识与共鸣、改善减灾态度、培养减灾价值观,进而激发减灾行动和减灾参与意愿,特别是激励人们就相关问题进行长期思考和持续行动改善。以上3方面进展,从总体上实现了对中国防震减灾工作存在的前述2点广泛不足的有益研讨与部分弥补推动尝试。参与式渭南地震情景构建行动研究示范,对国内相关工作具有抛砖引玉的作用,也为国际同类工作积累了中国经验。
