降雨型滑坡研究的发展现状与展望

本文从统计学研究和机理研究两个方面阐述了降雨型滑坡的研究历史和研究现状，其中又把降雨型滑坡机理研究按三个方面分别进行了论述，即降雨入渗引起的斜坡体内水-岩（土）力学作用（包括饱和与非饱和土力学）对斜坡稳定性的影响；降雨入渗引起的斜坡体内水-岩（土）物理化学反应对斜坡稳定性的影响和降雨型滑坡机理研究的数值模拟技术。通过上述论述可知，当前降雨型滑坡的研究虽然取得了丰富的成果，但是由于实际情况的复杂性，研究的成果还难以在实际的工程应用中对降雨型滑坡进行准确的预测预报，降雨型滑坡依然是有待深入探讨的前沿课题。文末对降雨型滑坡未来的研究方向进行了展望。

State-of-the-art study on landslides due to rainfall and the prospect

The history and the state-of-the-art study on landslides due to rainfall are expounded in the two aspects of statistics study and mechanism study. The discussions on the mechanism study in the paper include three parts： stability influence to slopes from the water-rock （soil） mechanic reactions （including saturated and unsaturated soil mechanics） due to rainfall infiltration in slopes; stability influence to slopes from the water-rock （soil） physical and chemical reactions due to rainfall infiltration in slopes and the numerical simulation technique in the mechanism study on landslides due to rainfall. Through the above discussions, they show that it is hard to forecast the happening of landslides due to rainfall, even though the great achievement has been made in the study on landslides. The study on the landslides due to rainfall is the front topic that should deeply be researched, and the coming study aspects are prospected.
