8.1折除时，首先将吊笼用停层装置停靠在待拆除的标准节的下两节上，操作人员上到吊笼顶，卷扬机松绳，用小吊杆将顶梁略向上提起，拔出顶梁横销，使顶梁值得徐徐降下，降到拆除节下一节中间框架角处，并重新穿上横销，这时用板手将标准节连接螺栓松开，将手摇起重机小吊杆钩挂在待拆节上框架用钢土，到吊笼内，用同样的方法拆下另一节标准节，然后将吊杆转向不影响升降机运行的方向，收紧起升钢丝绳，操作人员离开吊笼，打开锁止机构，使吊笼下降到下一个拆除位置，并将锁止机构锁死，人员重返笼顶，进行下一拆除循环注意：在吊笼运行时绝不允许有人员留在吊笼顶部或吊笼内

The presterssed anchor cable frame combined with backwall, drainage is necessary due to longtime sability and permanent utilization.Firstly,according the study of engineering of geology situation of the high slope, the mechanism of deformation failure and the major hazard of the high slope of PanMei is analysed comprehensively.And the whole slope is divided into two different geology enginnering areas:Western slope(1160 section plane -1240 section plane)and Eastern slope(1240 section plane -1320 section plane). The result of 3D numerical simulation is the same as geology judgement. Later,slope cut (1:0.75) is implemented based on the engineering comparison and criterion.Meanwhile, Limit equilibrium method , Monte Carlo Probabilistic slope stability the stability , Sensitivity analysis and Finent element method of for assessing the cutted slope stability is carried out. The result indicates that Western slope is instable, Eastern slope is relatively stable.So much attention should be paid to Western slope.Different reinforcement measures in different areas are given according to its stability and meet economical request. Gravity wall is introduced in accordance with landform in order to prevent small falling at the foot of the high slope ,which will be a threat to the high slope stability. Handling measure is also applied to Eastern slope. At last,FLAC3D numerical analysis shows the feasibility and reasonableness of the handling measure of the high slope.

论文首先研究了边坡的工程地质条件，全面分析边坡的变形破坏机制和边坡的主要地质灾害，将边坡分为西段不稳定边坡区(1160剖面～1240剖面)和东段相对稳定边坡区(1240剖面～1320剖面)，通过三维数值模拟再现了边坡在自重作用下的破坏机制和过程；在此基础上通过工程类比和规范要求，确定按照1：0.75进行放坡处理，并分析了放坡后边坡的稳定性状况，分别通过极限平衡法、蒙特卡洛法概率分析、参数敏感性分析和有限元稳定性计算等多种方法对边坡在各种工况下的进行稳定性研究，计算结果表明，西段边坡较之东段边坡稳定情况差，是边坡支护的关键之处，而东段边坡相对是稳定的；边坡的综合治理措施选用的是框架锚索并结合挡土墙和排水工程，治理设计根据不同区段的稳定性情况采用不同的支护结构，做到了经济合理的要求；在边坡的坡脚设置重力式挡土墙，防治边坡小规模的崩塌，会对上部的锚索支护护造成不利影响，进而影响边坡的稳定；东段边坡的填方区也给出了治理对策；最后通过三维显示拉各朗日有限差分程序(FLAC3D)模拟了高边坡放坡和支护效果，论证了治理措施的有效性和合理性。

The relationship in the Section Sitopsis i s consistent with the former investigation. Ae. mutica had a relatively clos e relationship with the species of the Section Comopyrum.Ae. uniaristata had a far relationship with the other two species of the Section Comopyrum,indicati ng that it should be excluded from this section. Ae. caudata and Ae. umbel lulata had a close relationship.

结果发现：（1）Sitopsis组内各物种的亲缘关系与前人的研究基本一致；（2）Ae.mutica与Comopyrum组的各物种亲缘关系较近；（3）Ae.uniaristata与同组的另两个物种亲缘关系较远，应将其从该组中独立出来；（4）Ae.caudata与Ae.umbellulata为亲缘关系较近的两个物种。

This is not surprising, given the closer proximity of Pengyang to the Asian inland dust sources; The average content of calcium carbonateis of Pengyang section is not only higher than that of central loess plateau, but also higher the west of Chinese Loess Plateau, which reflected Pengyang loess had been deposited by near Liupanshan\'s substances that contained more calcium carbonateis; The content of diffluent element of 10m depth in the section increased fast, which indicated that the modern eluviation and the leaching depth of loess may be stronger than our guess; The soil growth index can reflect the intensity of soil forming and the climatic changes; The "abrupt chang" of glacial and interglacial period was caused by strong soil-forming processes that enlarged the discrepancy of granularity between loess and paleosol. However, the magnetic susceptibility nearly cannot reflect the existence of S_8 and the magnetic susceptibility of S_7 is highest in the whole section, which is inconsistent with other studies that S_5 has the highest magnetic susceptibility.Thin-section examination shows that the micro-texture of the soil layers is divided into both cementing texture in S_7, S_5 and S_1, and granular texture in all others.

与其它剖面相比，彭阳剖面粒度总体上要比东部的洛川、西安，甚至西部的兰州、新疆东湾要粗；CaCO_3平均含量不仅高于黄土高原中部，也高于高原西部，反映出本剖面富含碳酸盐的六盘山近源沉积起到了很重要的作用；易溶元素含量在剖面10m处快速升高，淀积特征明显，反映出黄土受现代淋溶成土作用影响较大，黄土直立、疏松、多孔特性和高温与多雨组合的气候特点，使得元素淋溶、淀积的强度和深度超出了传统的认识和判断；烧失量与其它指标相比，不仅能区分冰期、间冰期；而且能够区分出次一级的冰阶、间冰阶，有较高的分辨率；土壤发育指数、红度能够反映土壤强度差异，是反映气候波动的较好指标；然而，磁化率不能反映古土壤S_8的存在，且S_7的磁化率在全剖面中最高，这与大多剖面S_5磁化率最高的特点不一致。4。

It involves the demand of the aged, the concept, content, influential factors of family elderly support, the concept, content, type, model and economic effect of public pension, theories searched from the study of Chinese elderly security. Section 2 introduces the history of family elderly support, analyses the reasons of the existence of it, expatiates on the factors that weaken the function of it, such as modernization of agriculture, population aging, family miniaturization, urbanization etc. section 3 introduces the history of the social old-age insurance in Chinese rural areas, analyses its impendency from the aspects of social stabilization, the rights and interests of the peasants, rural employment. Section 4 is the most important part of the thesis. It first refers to foreign practical experiences on rural elderly security, then demonstrates the elderly support at home which combines family elderly support and social elderly support, especially analyses the public pension.
