    研究方向 

    岩土体多尺度多场耦合研究是一个极具有交叉学科特点的研究方向,融汇了数学,物理、工程和地质多学科知识。近年,岩土工程和地质工程领域国际前沿研究朝着复杂化(水、热、力、化学多场耦合)和精细化(微观结构和微观力学)发展,即“岩土体多场和多尺度研究”,该领域超过一半的高水平论文(如Science, Nature,Geology,JGR-Solid Earth)围绕着地质灾害、多场耦合、和岩石破坏离散元模拟开展。岩土体在宏观上表现为相对连续,而微观上是由一系列颗粒和孔隙组成,并受水、热、力、化学等多场耦合作用。通过微观结构定量分析、微观力学和水热力多场耦合的方法可以有效地认识和解决各种岩土工程和地质工程问题,包括滑坡、泥石流、地面沉降、基坑稳定性和隧道开挖等涉及到多场作用的复杂问题。这些新理论和新方法具有广泛的科研和应用前景,有望在近几年实现双创和产业化。


    目前在研课题如下:

    1. 离散元工程数值法(DEM)理论、系统研发和应用。在研课题包括: a)DEM-LBM多场多相耦合理论和应用; b)地面沉降三维建模和模拟; c)多场多相耦合滑坡演化过程模拟; d)地铁隧道开挖模拟; e)基坑和桩土作用;f)水力压裂模拟;

    2. 岩土体微观结构定量分析及微宏观联系。在研课题包括: a)微观结构提取和定量分析; b)应力作用下的微观结构固定,实验方法和设备研发; c)颗粒和孔隙结构二维向三维转化理论,以及三维建模;d)砂土的微观破坏机制;


    相关研究基于创新的理论和自主研发的两套软件系统:1)岩土体多场作用三维离散元软件MatDEM,实现百万颗粒动态模拟;2)颗粒(孔隙)及裂隙图像识别与分析系统(PCAS),软件已较广泛应用,注册用户包括华南理工大学、浙江大学和中石化等高校和企业,已有数十篇相关论文发表,可参见:http://acei.cn/program/pcas
