前言/序言
     Several excellent books cover a wide spectrum of unsaturated soil mechanics and its applications to slope engineering, such as " Unsaturated Soil Mechanics in Engineering Practice" by Delwyn Fredlund, Harianto Rahardjo and Murray Fredlund published by Wiley and "llillslope Hydrology and Stability" by Ning Lu and Jonathan Godt published by Cambridge University Press. The new book "Rainfall Induced Soil Slope Failure: Stability Analysis and Probabilistic Assessment" by Lulu Zhang, Jinhui Li, Xu Li, Jie Zhang and Hong Zhu is a new addition which focuses on rain-induced slope failures from a soil mechanics approach. The authors of the book are all very active young researchers in the field of study.
  The new book concisely presents the fundamental mechanics behind rain- induced soil slope failures: infiltration and evapotranspiration in soil slopes, slope stability under rainfall infiltration, and hydro-mechanical coupled deformation. The concepts and analyses are presented clearly from the first principle with a strong physical sense. Some advanced topics, such as plastic analysis of hydro-mechanical coupled seepage and deformation in unsaturated soil slopes, are approached in a plain manner with hand-on tutorials, which is ideal for graduate students. The analysis of the stability of slopes with cracks is an excellent addition-practitioners are aware of the vital importance of cracks but few have the knowhow to quantify cracks on slopes and their effects on slope stability. The book overall provides the fundamental knowledge to deal with climate-slope interactions and resulting slope failures.
  The new book also systematically presents the uncertainties involved in the characterization and analysis of rain-induced slope failures. Methods for reliability analysis of slopes under rainfall, including probability concepts, identification of sources of uncertainty, stochastic finite element method and probabilistic model calibration, are introduced. This is a unique feature of the book-it is perhaps the only book that addresses both the mechanics and
  uncertainties behind rain-induced slope failures.
  I believe that Rainfall Induced Soil Slope Failure: Stability Analysis and Probabilistic Assessment will serve as an excellent reference for educators, university graduate students, researchers and practitioners.    
				
 
				
				
					降雨誘發滑坡:穩定分析與概率評價(英文版)  圖書簡介  《降雨誘發滑坡:穩定分析與概率評價》(Rainfall-induced Soil Slope Failure: Stability Analysis and Probabilistic Assessment) 是一本深入探討降雨對土質邊坡穩定性影響的專業著作。本書旨在為岩土工程、地質災害防治、水利水電以及土木工程領域的專業人士、研究人員和高級學生提供一個全麵、嚴謹且前沿的分析框架和技術工具。  本書的核心目標是彌閤傳統確定性邊坡穩定性分析方法與日益復雜的實際工程風險評估需求之間的鴻溝。它不僅係統梳理瞭降雨如何通過改變土體水文地質條件(如孔隙水壓力、有效應力、土體強度)進而觸發滑坡的基本機理,還重點聚焦於如何運用先進的數學模型和概率論方法對這些時變性的失穩風險進行量化和預測。  全書結構嚴謹,邏輯清晰,共分為若乾核心部分,層層遞進地構建起從機理認知到風險量化的知識體係。   第一部分:基礎理論與降雨作用機理  本部分首先迴顧瞭土力學和岩土工程學的基本原理,特彆是關於邊坡抗滑穩定性的傳統極限平衡理論(如瑞典條分法、Bishop法等)和基於應力-應變分析的強度理論。在此基礎上,本書詳細剖析瞭降雨過程的復雜性及其對土體的影響機製:  1. 水力耦閤效應: 深入探討瞭降雨入滲過程,包括地錶徑流、滲透深度、地下水位動態變化等,如何影響邊坡內部的水力梯度。 2. 孔隙水壓力演化: 這是降雨誘發滑坡的關鍵驅動因素。本書闡述瞭瞬態和非飽和滲流理論如何應用於計算降雨驅動下的孔隙水壓力升高,特彆是對不飽和土區的影響機製。 3. 土體強度參數的瞬態變化: 分析瞭有效應力原理在含水率變化時的適用性,以及降雨如何通過降低土體黏聚力和內摩擦角(尤其在細顆粒土中)來降低邊坡的抗剪強度。   第二部分:確定性穩定性分析模型的拓展  在理解瞭降雨機理後,本書轉嚮瞭將這些水文條件納入傳統穩定性評估的框架中。本部分側重於如何將降雨模型(如Boutrup模型、Green-Ampt模型等)的輸齣,作為輸入參數嵌入到極限平衡或有限元分析中:  1. 瞬態穩定性分析: 介紹瞭如何針對不同降雨強度和曆時,計算邊坡安全係數(FS)隨時間變化的麯綫,從而確定臨界降雨閾值。 2. 非飽和土邊坡分析: 重點討論瞭Richard方程在模擬非飽和土滲流中的應用,以及如何利用基質吸力(Matric Suction)的概念來增強邊坡在乾燥或輕度濕潤條件下的穩定性,並評估降雨飽和後吸力急劇下降帶來的風險。 3. 邊坡響應時間: 探討瞭降雨與滑坡發生之間的時間滯後效應(Time Lag),並建立瞭預測這種滯後的經驗模型和基於物理過程的模型。   第三部分:概率性風險評估框架  本書的獨特價值和前沿性主要體現在第三部分,即引入概率論和不確定性分析方法,對降雨誘發滑坡的風險進行量化:  1. 不確定性來源識彆: 詳盡列舉瞭在降雨誘發滑坡評估中存在的主要不確定性來源,包括降雨量和強度數據的隨機性、土體材料參數(如滲透係數、強度參數)的空間變異性,以及模型本身的結構誤差。 2. 可靠性指標的計算: 係統介紹瞭常用的可靠性分析方法,如一階可靠性方法(FORM)、二階可靠性方法(SORM),以及更廣泛應用的濛特卡洛模擬(Monte Carlo Simulation, MCS)和隨機有限元方法(Random Finite Element Method, RFEM)。 3. 概率密度函數的選擇與校準: 討論瞭如何根據現場數據和經驗,為降雨量、地下水位和土體參數選擇閤適的概率分布函數(如正態分布、對數正態分布、Weibull分布等)。 4. 概率風險的解釋與應用: 最終,本書指導讀者如何將計算得到的失效概率(Probability of Failure, Pf)轉化為實際的風險評估指標,如風險值(Risk Value),為工程決策提供科學依據,例如確定最優的監測預警閾值。   第四部分:案例研究與工程實踐  為瞭驗證和深化理論,本書包含瞭一係列基於真實世界數據的綜閤性案例研究:   典型降雨事件迴溯分析: 選取瞭幾個國際知名的降雨誘發滑坡案例,運用書中介紹的概率模型對其失穩過程進行反演分析,評估瞭不同模型參數對結果的影響。  實時監測與預警係統的集成: 討論瞭如何將概率風險評估結果與實時傳感器監測數據(如降雨量、孔隙水壓力計讀數)相結閤,建立動態的、概率性的邊坡預警係統。  工程措施的風險效益分析: 探討瞭如何利用概率評估結果來量化排水、加固等減災措施對降低未來失效風險的有效性。  本書的特點:   跨學科整閤: 成功地將水文工程、岩土力學和應用統計學緊密結閤。  注重前沿: 詳細介紹瞭非飽和土力學和隨機有限元等現代分析工具在邊坡工程中的具體應用。  實用性強: 提供瞭清晰的分析步驟和可操作的數學框架,便於工程師在實際工作中應用。  適用讀者:  本書是岩土工程師、地質災害風險評估專傢、水文地質工程師、土木工程研究生及相關領域研究人員的必備參考書。它不僅是理論學習的權威教材,更是解決復雜工程問題的實用工具手冊。
