The maximum run-out distance is 3200m. The three cases are studied from the Niuquangou rockslide-debris flow at the south west segment of the main seismic fault, the Chengxi rockslide at the middle segment of the main seismic fault and the Donghekou rockslide-debris flow at the north east segment of the main seismic fault.The three cases illustrates following common characteristics:(1)parent rockmass is broken under long geologic processing and weathered;(2) Rockmass was separately expanded and thrown under long-period strong ground vibration in which the vertical motion was predominant along the main seismic fault;(3)sliding mass was crashed at the exiting zone and transferred to fragment material;(4) The secondary landslide was triggered underneath the exiting zone due to the powerful crashing and shaving processes that provides more mass to debris body and cushion shape;(5) The a long run-out distance fragment flow is occurred under air layer lubrication. The air layer was pressed and turbulently flowed in the narrow-shaped valley, or laminarly flowed in the extensive flatland.
本文重点解剖了位于地震破裂带南西段的汶川映秀牛圈沟滑坡-碎屑流、位于地震破裂带中段的北川城西滑坡和位于地震破裂带北东段青川东河口滑坡-碎屑流3个典型实例,认为具有如下特征:1)岩性条件:母岩遭受长期构造动力作用,呈碎裂岩体,后期被强烈风化,岩体极为破碎;(2)抛掷效应:位于汶川地震主断裂带或附近,垂直加速度大于水平加速度,强地面运动持时长,岩体发生振胀和抛掷;3)碰撞效应:上部滑坡体发生高位剪出和高位撞击,致使岩体碎屑化;(4)铲刮效应:撞击作用导致下部山体被铲刮,形成次级滑坡,为碎屑流体提供了足够展翼和抛洒物源体积;5)气垫效应:碎屑化岩体快速抛掷导致下部沟谷空气迅速谷状圈闭和向下紊流,形成气垫效应,或者,在下部地形开阔地带压缩空气呈层流状态致使滑体凌空飞行。

Sedimentary facies model for mixed sediments of recent reefoid carbonates and siliciclastics is developed from the facies model of fringing and barrier reefs. Based on the sedimentary facies and textures, mixed sediments may be subdivided into 5 types as follows: 1 reef base mixed sedimentary rocks and reef framework mixed sedimentary rocks; 2 reef flat sand-gravel mixed sedimentary rocks; 3 backreef beach-dune gravel-sand mixed sediments; 4 backreef lagoonal sand mixed sediments ; and 5 reef front littoral sand mixed sediments.
礁源与陆源混合沉积相模式是从岸礁一堡礁相模式基础上发展而来,根据其沉积相和沉积结构特徵可以分为5种混合沉积:①礁基混积岩和礁格架混积岩;②礁坪砂砾屑混积岩;③礁后海滩-沙提砾砂屑混合沉积;④礁后泻湖砂屑混合沉积;⑤礁前浅海砂屑混合沉积。

Three kinds of cutting material were selected to machine stainless steel machining experiment such as ceramic cutting tools, cermets cutting tools and coated carbide cutting tools, in which the best range of each kind of tool material was founded. For example, LT55 was suitable to be machine lCrl8Ni9Ti as the cutting speed surpasses 120m/min and have a good wearable property.(3) Surface roughness was measured under different cutting conditions. Feed rate played the most important role in impacting surface roughness, and then cutting speed.(4) Chip patterns in different cutting speed with various cutting materials were analyzed. With the increase of turning speed, chip became shorter and was easy to be broken. For instance, serration chip appeared in high sped turning stainless steel with LT55;(5) Work hardening of austenitic stainless steel was analyzed.
陶瓷刀具LT55适合在Vc=120m/min以上切削加工不锈钢,耐磨性好;③通过试验研究了不同刀具材料高速车削加工1Cr18Ni9Ti不锈钢时的表面粗糙度,其中进给量对表面粗糙度的影响最为显著,其次为切削速度;④分析了不同刀具材料在不同切削速度下加工1Cr18Ni9Ti不锈钢的切屑形态,随着车削速度的提高,切屑变短且易断屑,其中LT55陶瓷刀具切削加工时产生了锯齿状切屑;⑤分析了奥氏体不锈钢的加工硬化机理及其对刀具磨损的影响;⑥根据试验结果分析在不同切削条件下切削不锈钢的刀具磨损形式及其磨损机理。

The results showed that at the same concentrations, the total amount of test PAHs adsorbed by the K. candel and A. marina leaf litters had no significant difference, in spite of their decomposition status. The adsorbed amount of the PAHs tended to increase with their increasing concentrations. The litters had a higher adsorption rate of or exhibited selective adsorption to phenathrene and chrysene when the PAHs concentrations were lower, and had a higher adsorption rate of benzo perylene when the PAHs concentrations were higher.
结果显示:在同等PAHs浓度下,秋茄和白骨壤落叶碎屑对4种PAHs的吸附总量相近,树种间或分解状态间的吸附差异不显著;随着PAHs浓度的增加,2种红树植物落叶碎屑对4种PAHs的吸附率均呈现逐渐增加的趋势;PAHs浓度较低时,落叶碎屑对和菲有较高的吸附率或选择性吸附,PAHs浓度较高时,落叶碎屑对苯并芘吸附率提高。
