With the rapid development of information technology, the virtual simulation technologies have been widely applied to various fields. Due to the limitations of traditional experimental teaching in money, laboratory space, instrument and manpower, the teaching and learning may be seriously affected. With the aid of virtual simulation technologies, however, these troubles can be removed or alleviated. With the virtual simulation experimental laboratory of civil engineering in Beijing Jiaotong University taken as an example, the virtual simulation experimental modules of soil mechanics were developed partially by the company and partially by ourselves. It is believed that by combining the virtual simulation experiments and the physical experiments, the limitations of traditional physical laboratory tests can be removed or alleviated. The combination of virtual simulation experiments and the physical experiments can improve the teaching and learning quality of civil engineering experiments.
