【摘要】：进入新的时代以后,我国在各方面的都取得了较为巨大的前进,特别实在经济方面也得到了较为快速的发展,我国对基础建设的投入力度和投入规模在不断的加大。尤其是对较大的关系国计民生的基础建设尤为突出,这也使得我国在城市建设、轨道交通、矿山建设、水利水电等基础工程方面所取得的成绩更加迅猛和高效。但在基础建设取得较大成就的过程中,也出现人与自然的不和谐,众多的问题出现在城市的发展建设中来。其中在最近几年的发展过程中,边坡问题伴随着城市的发展逐步显现。其发生的概率也伴随着城市建设的不断扩张,呈现出逐年增多的趋势。所以对于这方面的深入的重要性逐步的加大。在不断的探索和总结过程中,发现顺层滑坡在现在的各类建设出现的频率和问题较多,同时也是对生产建设和各类发展规划带来问题和产生灾害性后果较严重的一种滑坡形式。此类滑坡问题一旦出现或是发生将严重影响建设的发展进度,同时对人们生命健康也是严重的威胁。可见对此类滑坡问题的研究也是比较重要的,认清类似顺层滑坡的发生机理、滑坡的特性及滑坡的发生过程是十分必要的。对于类似的滑坡来说,其岩石或是土体的本身结构特性,即它们的边坡走向和该类成岩或是堆积体的走向肯定是一致的,更甚者大部分的成岩或是堆积体的倾向坡角还大于其所在的斜坡的坡度。在这种情况下,由于受到地球的对物体所产生的重力作用,会逐步的出现类似变形、下滑或是垮塌等破坏形式。从破坏的机理上区分大致有这么几种破坏形式:一是由滑移到弯曲的变形,二是由于自身堆积体如岩石等局部出现的开裂变形而遭到破坏,三是从弯曲到拉伸而发生了破坏。根据不同的堆积方式和坡体的成因进行针对性的研究分析,并加大研究力度,同时做好相应的总结分析,尤其是对可能出现的较大危及人身安全及给社会民生带来一定破坏和影响的地质灾害进行研究和治理,并且使之得到有效的治理。目前针对多因素条件下济南市地区顺层滑坡特征的研究成果在国内外还比较不多见,比较具有研究价值。本文依托济南市历城区某山体景区山体滑坡灾害治理项目,调查查明区内山体滑坡空间分布、规模,分析形成机理及影响因素等,分析多因素影响条件下济南市某山体顺层滑坡特征,对其稳定性进行评价,制定出滑坡灾害治理的治理方案,为灾害治理提供设计依据。通过对本工程的深入研究和治理,对本地区的类似项目起到了重要的理论指导和实践指导,为有效推动区域灾害的防控也是有积极意义的。因此在方案的设计方面也比较注重设计的创新与实际的相结合,力争使本设计有好的突破。
[Abstract]:After entering the new era, China has made great progress in all aspects, especially in the real economy has also been relatively rapid development. China's investment in infrastructure and investment scale is constantly increasing, especially for the larger national economy and people's livelihood infrastructure is particularly prominent, which also makes our country in urban construction, rail transit, mine construction. The achievements in basic engineering such as water conservancy and hydropower are more rapid and efficient, but in the process of making great achievements in infrastructure construction, there is disharmony between man and nature. Many problems appear in the development and construction of cities. In the recent years, slope problems gradually appear along with the development of cities, and the probability of occurrence is accompanied by the continuous expansion of urban construction. Showing a trend of increasing year by year. So the importance of this in-depth gradually increased. In the process of continuous exploration and summary, we found that there are more frequency and problems of bedding landslide in all kinds of construction now. At the same time, it is also a kind of landslide form which brings problems and disastrous consequences to production construction and all kinds of development planning. Once this kind of landslide problem appears or occurs, it will seriously affect the development progress of construction. At the same time, it is also a serious threat to people's life and health. Therefore, it is important to study this kind of landslide, and to recognize the occurrence mechanism of similar bedding landslide. The characteristics of landslide and the occurrence process of landslide are very necessary. For similar landslides, the structural characteristics of rock or soil are very important. That is, their slope strike is definitely the same as that of this type of diagenesis or accumulation, and even more, the inclined slope angle of most diagenetic or accumulative bodies is greater than the slope of the slope in which they are located. In this case. As a result of the Earth's gravitational action on the object, will gradually appear similar deformation. According to the failure mechanism, there are several types of failure: one is the deformation from sliding to bending. The second is due to the local cracking and deformation of their own accumulations such as rocks and the third is the failure from bending to stretching. According to the different stacking methods and the cause of formation of slope body targeted research and analysis. And increase the strength of research, at the same time do a good job of the corresponding summary and analysis, especially on the possible occurrence of a greater threat to personal safety and bring certain damage and impact on the social and livelihood of the geological hazards for research and management. At present, the research results on the characteristics of bedding landslide in Jinan under the conditions of multiple factors are still relatively rare at home and abroad. Based on the project of landslide disaster control in a mountain area in Licheng District of Jinan City, this paper investigates and finds out the spatial distribution, scale, formation mechanism and influencing factors of landslide in this area. This paper analyzes the landslide characteristics of a mountain body in Jinan under the influence of many factors, evaluates its stability, and formulates the control scheme of landslide disaster management. Provide design basis for disaster management. Through the in-depth study and management of the project, it has played an important theoretical and practical guidance for similar projects in the region. In order to effectively promote the prevention and control of regional disasters, it is also of positive significance. Therefore, in the design of the project, we also pay more attention to the combination of design innovation and practice, and strive to make a good breakthrough in this design.
