【摘要】：進入新的時代以后,我國在各方面的都取得了較為巨大的前進,特別實在經(jīng)濟方面也得到了較為快速的發(fā)展,我國對基礎建設的投入力度和投入規(guī)模在不斷的加大。尤其是對較大的關系國計民生的基礎建設尤為突出,這也使得我國在城市建設、軌道交通、礦山建設、水利水電等基礎工程方面所取得的成績更加迅猛和高效。但在基礎建設取得較大成就的過程中,也出現(xiàn)人與自然的不和諧,眾多的問題出現(xiàn)在城市的發(fā)展建設中來。其中在最近幾年的發(fā)展過程中,邊坡問題伴隨著城市的發(fā)展逐步顯現(xiàn)。其發(fā)生的概率也伴隨著城市建設的不斷擴張,呈現(xiàn)出逐年增多的趨勢。所以對于這方面的深入的重要性逐步的加大。在不斷的探索和總結過程中,發(fā)現(xiàn)順層滑坡在現(xiàn)在的各類建設出現(xiàn)的頻率和問題較多,同時也是對生產(chǎn)建設和各類發(fā)展規(guī)劃帶來問題和產(chǎn)生災害性后果較嚴重的一種滑坡形式。此類滑坡問題一旦出現(xiàn)或是發(fā)生將嚴重影響建設的發(fā)展進度,同時對人們生命健康也是嚴重的威脅�？梢妼Υ祟惢�坡問題的研究也是比較重要的,認清類似順層滑坡的發(fā)生機理、滑坡的特性及滑坡的發(fā)生過程是十分必要的。對于類似的滑坡來說,其巖石或是土體的本身結構特性,即它們的邊坡走向和該類成巖或是堆積體的走向肯定是一致的,更甚者大部分的成巖或是堆積體的傾向坡角還大于其所在的斜坡的坡度。在這種情況下,由于受到地球的對物體所產(chǎn)生的重力作用,會逐步的出現(xiàn)類似變形、下滑或是垮塌等破壞形式。從破壞的機理上區(qū)分大致有這么幾種破壞形式:一是由滑移到彎曲的變形,二是由于自身堆積體如巖石等局部出現(xiàn)的開裂變形而遭到破壞,三是從彎曲到拉伸而發(fā)生了破壞。根據(jù)不同的堆積方式和坡體的成因進行針對性的研究分析,并加大研究力度,同時做好相應的總結分析,尤其是對可能出現(xiàn)的較大危及人身安全及給社會民生帶來一定破壞和影響的地質(zhì)災害進行研究和治理,并且使之得到有效的治理。目前針對多因素條件下濟南市地區(qū)順層滑坡特征的研究成果在國內(nèi)外還比較不多見,比較具有研究價值。本文依托濟南市歷城區(qū)某山體景區(qū)山體滑坡災害治理項目,調(diào)查查明區(qū)內(nèi)山體滑坡空間分布、規(guī)模,分析形成機理及影響因素等,分析多因素影響條件下濟南市某山體順層滑坡特征,對其穩(wěn)定性進行評價,制定出滑坡災害治理的治理方案,為災害治理提供設計依據(jù)。通過對本工程的深入研究和治理,對本地區(qū)的類似項目起到了重要的理論指導和實踐指導,為有效推動區(qū)域災害的防控也是有積極意義的。因此在方案的設計方面也比較注重設計的創(chuàng)新與實際的相結合,力爭使本設計有好的突破。
[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.
