【提要】 在建立邊坡穩(wěn)定問(wèn)題的分析模型時(shí)，要建立計(jì)算程序易于識(shí)別的邊坡地層模型?，F(xiàn)有邊坡計(jì)算軟件的地層建模方法有直線段地層建模法、折線地層建模法和區(qū)域地層建模法。前兩種方法比較繁瑣，可視化程度低?；谲浖夹g(shù)的發(fā)展，展望了邊坡軟件地層建模方法的發(fā)展趨勢(shì)，提出采用鉆孔柱狀圖自動(dòng)建立地層分布模型的方法，能實(shí)現(xiàn)高效的建模功能，大大方便邊坡穩(wěn)定分析的地層建模。

Stateoftheart and Development of Stratum Modeling for Slope Stability Analysis

Abstract:When building analysis model to calculate the slope stability,the stratum model should be liable to discriminate by the calculation software.The existed methods including the straight line stratum modeling,the breaking line modeling and region stratum modeling are introduced .The former two methods are complex and the visualizations of them are poor.The trend of development is presented.It is suggested that the auto stratum modeling method using the holedrilled histogram can realize the modeling expeditiously and facilitate the modeling to calculae the slope stability.
Keywords:slope stability analysis； stratum modeling; polygon; drill hole
