土力学实验是土力学课程体系的重要组成部分，在加深理论理解、锻炼实验能力、激发创新精神和培养工程意识等方面有不可替代的作用。通过对多所高校土力学实验教学现状的调研分析，系统性地提出线上线下混合，课前课后多阶段贯穿，虚拟仿真、数值模拟与实验教学深度融合的多元混合式土力学实验教学改革方案，详细阐述改革措施，构建"五位一体"土力学实验课程体系。依托MOOC、实验空间、PFC等信息教学手段打造线上线下双通道、多维度学习空间，开发设计性、创新性实验项目，制定"量""效"并行的考核机制，充分激发学生学习兴趣，挖掘科研潜力，提高工程能力，教学满意度显著提高。以此推动西南大学土力学建设国家级一流课程的进程，为土力学实验教学改革与创新提供参考。

Soil mechanics experiment is an important part of soil mechanics curriculum system, and it plays a unique role in deepening theoretical understanding, training ability of experimental, stimulating innovation ability and cultivating engineering consciousness. Based on the investigation and in-depth analysis of the current situation and existing problems of soil mechanics experiment teaching in many colleges, the paper systematically proposes the teaching reform scheme of soil mechanics experiment including the combination of online and offline, multi-stage before and after classes, and a deep integration of virtual simulation, numerical simulation and experimental teaching. The reform plan for experimental teaching of soil mechanics is elaborated in detail:the construction of a "five-in-one" soil mechanics experimental curriculum system, relying on MOOC, experimental space, PFC and other information teaching methods to create online and offline dual-channel, multi-dimensional learning space, develop design and innovative experimental projects, formulate "quantity" and "efficiency" parallel assessment mechanism, fully stimulate students’ learning interest, tap scientific research potential, improve engineering ability, and significantly improve teaching satisfaction. In this way, the process of building a national first-class curriculum of soil mechanics in Southwest University will be promoted, and it will provide reference for the reform and innovation of the teaching of soil mechanics experimental.
