崩塌

The disaster of rockfall has became one of research subject which is second only to slope stability, particularly in engineering of high and steep rock slope.

在边坡尤其是高陡岩质边坡工程中，崩塌落石灾害已经成为仅次于边坡稳定的研究课题之一。

The main geohazard types of this area are landslide, rockfall and debris flow.

崂山区地质灾害及隐患点发育的类型主要是滑坡、崩塌和泥石流。

At the other hand, geological hazards in China, such as landslide and rockfall, are becoming more and more serious. Therefor, it is emergent to apply the latest technology of GIS to the researches on the geological hazards.

同时，我国山区崩塌、滑坡等灾害日益突出，因此，将最新的地理信息系统技术应用到地质灾害研究就显得越来越迫切。

By this way, the extend and degree of the masses were illustrated intuitionally and it was made out that the main destroying form was toppling rockfall .

在分析砂、泥岩特性的基础上，通过离散元数值分析，研究了万县长江库岸危岩在不同工况下的稳定性，直观地揭示出危岩在不同工况下的破坏程度，得出危岩的主要破坏形式为倾倒式崩塌，并总结出危岩的大规模破坏发生在蓄水回水期，为三峡危岩治理的对策及时间提供了有价值的参考。

Combining GIS with statistic methords as a space analyzing tool, a risk-zooning map of rockfall hazard of Isahaya, Japan has been made.

2通过利用GIS作为分析工具并结合相关的统计分析方法作为研究手段，获取了谏早市完整的崩塌灾害危险性区划图。

In this paper, the authors classify the problems into landslide, rockfall and collapse of river bank, and relevant influence factors, for example, geo-material properties, weathering and surface/ground water, and finally suggest some control measurements.

文章根据多年积累的大量实际资料分析研究，总结了南充市区的主要斜坡工程地质灾害类型为滑坡、崩塌及岸坡失稳。其中以滑坡最为常见；影响斜坡工程地质问题产生的主要因素为岩土性质、风化作用和水的作用；针对不同的斜坡工程地质问题，提出了具体的工程防治对策。

Finally, in Chapter 5, the mechanics of sandpile avalanche has been studied using a horizontal vibration as an outside perturbation.

第五章中，通过可调的水平振动作为扰动，我们研究了沙堆受外力崩塌时的物理机理。

Proposed an one-dimensional sandpile model which include avalanche probability, and performed computer simulation by cellular automata method.

提出了一个含崩塌概率的一维沙堆模型，并用元胞自动机方法对该模型进行计算机模拟。

On the other hand, the surface of the sandpile is not able to resist large extrusion stress, which can be an additional criterion to describe the mechanics of sandpile avalanche.

另外，结果显示，沙堆表面也对崩塌也很敏感，表面不能承受很大的挤压，这个结果很类似液体的行为。

The innovation of our rearch:(1) A new one-dimensional sandpile model is set up, in this model avalanche probability is introduced.(2) Emulational simulation is performed with cellular automata method, and numerical analyse is carried out according the simulation result.(3) With the simulation result, We not only explained the SOC phenomena appearing in real sandpile, but also revealed a new path to SOC.

本文的创新之处在于：建立了一个含崩塌概率的一维沙堆模型；用元胞自动机的方法对模型进行了仿真模拟，并对仿真结果进行了数值分析；我们的模拟结果不仅很好地解释了真实沙堆中出现的自组织临界现象，而且揭示了一条通往自组织临界性的新途径。
