抗滑桩滑坡推力和桩前滑体抗力分布规律的研究

根据我国一些抗滑桩模型试验和现场试桩实测试验资料分析结果，针对滑坡体岩土体性质不同，提出和推导了相应的滑坡推力和土体抗力分布函数，并列成图表，便于应用时查取。一般来说，与目前国内外习惯采用的分布图式相比，滑坡推力合力作用点均有所降低，而土体抗力作用点均有所提高，更符合抗滑桩实际受力状况。实例分析比较表明，选择适当的分布函数，将使抗滑桩设计更为经济合理，从而提高滑坡治理设计水平。

STUDY ON DISTRIBUTION LAWS OF LANDSLIDE-THRUST AND RESISTANCE OF SLIDING MASS ACTING ON ANTISLIDE PILES

The different distribution functions of the landslide-thrust and the resistance of soil or rock are studied and deduced based on the results of model test and field test of antislide piles in China. Meanwhile,to beconvenient,the study results are provided with a table. Generally speaking,compared with the distributiondiagrams that people are accustomed to using at present,the presented results show that the resultand thrust point becomes lower and the resultand resistance point higher,which coincides with the practical state of forces acting on antislide piles. An example shows that the design of antislide piles will be more economical and reasonable by choosing appropriate distribution functions. Therefore,the design level of landslide control will be improved.
