摘要中国的地质灾害在亚洲来说也算比较严重的。在中国发生过的比较大的自然 灾害有 “三年自然灾害”、唐山大地震、汶川地震、1997 年的特大洪水等。特 大自然灾害的发生往往伴随着气候的异常，可能会引发特大洪水、泥石流、滑坡 等次生自然灾害，严重威胁人们的生命财产安全。不仅如此，而有时小小的气候 变化，可能会引发特大次生灾害，这些像泥石流、滑坡、地面沉降等次生灾害成 为威胁人们生命安全的主要原因。据估计，中国的地质灾害，造成将近亿元的经 济损失,次生灾害造成伤亡不计其数。在各种自然次生灾害中，滑坡占有非常大 的比重，说明滑坡是最容易引发的次生灾害。面对无情的自然灾害，我们从来没 有怠慢过。我们也为共同预防地质灾害，发现并及时上报作最大的努力。 69263

滑坡作为次生灾害中占有较大比重的灾害，当然是我们预防的重中之重。如 何有效的预测滑坡变形对人们的生命财产安全有至关重要的意义，而多项式拟 合是处理大量变形数据的有效方法，选择合适的拟合函数，对于分析滑坡采集的 大量数据，通过数据分析，确定滑坡可能性大小有着至关重要的关系。

The application of polynomial fitting in the analysis of deformation data

Abstract

Geological disasters in China are more serious in Asia. "three years of natural disasters"、 the Tangshan earthquake, Wenchuan earthquake in 1997, is the relatively

large natural disasters in china. Massive natural disasters happen often with the exception of climate, could trigger flooding, mud-rock flows, landslides and other secondary natural disasters, serious threats to people's life and property safety. Not only this, but sometimes a small climate change, may lead to serious secondary disasters, such as debris flows, landslides, ground subsidence and other secondary disasters as a threat to people's lives and safety of the main reasons. It is estimated that China's geological disasters, resulting in nearly billion yuan of economic losses, secondary disasters caused countless casualties. In a variety of natural secondary disasters, the landslide occupies a very large proportion, which shows that the landslide is the most easily triggered secondary disasters. In the face of relentless natural disasters, we never neglect too. We also work together to prevent geological disasters, discovered and reported in a timely manner to make the greatest efforts.

Landslide as a secondary disaster in the possession of a large proportion of the disaster, of course, is the most important of our prevention. How to effectively predict the landslide deformation is vital to people's life and property safety, and polynomial fitting is an effective method to deal with a large number of deformation data of, choose the appropriate fitting function, for the acquisition of landslide, a large number of data analysis, through data analysis, determine the landslide probability has a crucial relationship.
