摘 ?要:滑坡動力學(xué)的研究是一個熱門領(lǐng)域也是一個難點(diǎn)。在該領(lǐng)域中,滑坡速度的求取是一個相當(dāng)棘手的問題,各類速度求取方法也是層出不窮,但一直缺少一個統(tǒng)一的分類。分類主要有理論計算方法、工程類比方法、數(shù)值模擬方法3類,以便廣大學(xué)者和工程技術(shù)人員參考。通過對滑坡速度求取方法分類以及各類方法的分析類比,指出了今后滑坡速度求取方法的可能的研究方向及側(cè)重點(diǎn)。

Abstract: The study of landslide dynamics has always been a hot area and it is also an extremely complicated problem. In this field, the speed of landslide is a very difficult problem to solve. The speed of all kinds of methods is also endless, but there is always a lack of a unified classification. This article summarizes and classifies the methods that are widely used today. The classification mainly includes theoretical calculation method, engineering analogy method and numerical simulation method, so that the majority of scholars and engineering technicians can refer to it. Through the classification of landslide velocity estimation methods and the analysis analogy of various methods, the possible research directions and focuses of future landslide velocity calculation methods are pointed out.
Key Words: Landslide speed; Landslide disaster prediction; The method of seeking; Classification
2 ?結(jié)論
通過對各種滑速求取方法的總結(jié)分析,給出了一種較為合理的分類方法,闡述了各類方法的基本原理及應(yīng)用。在充分分析對比各類方法基礎(chǔ)上,可以看出滑速求取以后將沿著以下幾個方向進(jìn)行。
(1)理論計算方面,傳統(tǒng)的考慮單因素的計算結(jié)果很難對真實的滑坡運(yùn)動過程再現(xiàn),多因素耦合條件下的分析計算將是今后研究的重要方向。
(2)工程類比方面,參數(shù)的選取直接決定結(jié)果的準(zhǔn)確性,準(zhǔn)確把握參數(shù)的選擇,應(yīng)用大量滑坡數(shù)據(jù)的分析對比結(jié)果來對參數(shù)的選擇加以限制與校準(zhǔn),這將有利于滑坡運(yùn)動過程的準(zhǔn)確把控。
