软硬互层型边坡变形监测、预测及长期稳定性研究

摘要

以彭家湾软硬互层边坡为例，通过对监测数据的分析，说明边坡的现状。利用监测数据，对未来边坡的变形进行预测，在此基础上对其稳定性进行初步评价。利用斋藤模型对边坡的长期稳定进行了分析。通过这手段建立一套软硬互层型边坡变形监测、预测及长期稳定性分析的方法。通过以上方法对彭家湾软硬互层变形的现状，未来和长期稳定性进行了研究得出的结论为：彭家湾软硬互层边坡的现状稳定，未来一定时期内也是稳定的，并且长期稳定性良好。%This paper examples pengjiawan slopes with interbeddings of soft and hard rocks ,through analyzing the monitoring data ,illustrates the present situation of the slope .Then using the monitoring data ,the deformation of the future slope is predicted ,and on this basis the stability of the future slope is evaluted preliminarily .Finally using saito model the long-term stability of the slope is analyzed .By this means to a set of method of deformation monitor ,deformation forecast and long-term stability studies of slopes with interbeddings of soft and hard rocks is established .Through studying the Pengjiawan slope’s deformation present and future and long-term stability by the above method ,the conclusions are :the situation of Pengjiawan slope with interbeddings of soft and hard rocks is stable in the present and a certain period of time in the future ,and the long-term stability is good .
