- 摘要:
- 滑坡治理工程的设计主要依据滑坡面及滑体方量，滑坡的上表面一般很容易得到，而下表面则根据地形图中等高线来确定，但是要得到准确的滑坡面则相对较难，常用的方法是选择适当的个别点进行钻探，测得该点处滑坡厚度，再由此模拟滑坡面。以四川省古蔺县蔺双公路K1+100 m处滑坡的滑动面（带）为例，采用多元统计的趋势面分析方法将滑坡面模拟成空间的一个曲面，求出曲面后则可计算滑坡推力、设计相应的加固方法，还可以通过滑动曲面计算滑坡的总方量。
- Abstract:
- The design in landslide treatment is mainly based on the sliding surface and volume.Usually the upper landslide surface can gain easily, and the lower can gain by the contour in the topographic map.However, it is more difficult to get the accurate surface.The usual method is surveying the thickness of landslide by drilling several places, then simulating the landslide surface.This paper takes the slide surface analysis of landslide at K1+100 along Gulin-Lishuang highway in Sicuan Gulin county as an example, simulates the landslide surface to the spatial curving surface by the application of trend surface analysis of statistics, calculates the propulsion of landslide, designs the improvement method and calculates the total landslide volume according to the slide spatial curving surface.
