Retrogressive landslide is one of the common types of slope disaster in the highway construction. K7 landslide caused by engineering construction is a medium landslide which occurred in highway of Jiangkou to Weng'an in Guizhou province. Based on the engineering geology analysis, the engineering geological conditions of the landslide, the landslide stability influence factor and failure mechanism was analyzed. Furthermore, we calculated the landslide stability coefficient and evaluated the influence of excavation and the rainfall on landslide stability quantificationally, coming to the conclusion that excavation and rainfall had great influence on state stability and the stable factor of the landslide , and the excavation and rainfall will larger influence on safety coefficient and stability state. And we took the comprehensive management measures including anti-slide pile, drainage, closing the cracks of the slope and so on to treat the landslide. The monitoring results show that the cause analysis of the K7 landslide is correct, and the comprehensive treatment scheme is reasonable.

The open laboratory management, based on Internet plus technology, realized the dynamic management to book laboratory work ahead of schedule and the network management to laboratory resources, by taking the laboratory information management platform as the frame, assorting student safety access system, intelligent door access system, experiment booking management system, experimental charging system, as well as the platform of experimental data storage and sharing. The practice showed that, open laboratory which was established by the "internet+" technology could break the traditional closed laboratory management concept. Students could check the laboratory's resource distribution at any time, so they could arrange their experiment time more freely and reasonably, the efficiency of laboratory resources could balance and adjust more effectively too. At the same time, it could realize the management of all kinds of data statistics and information, such as laboratory teaching, laboratory opening, instrument and equipment and so on. All of these could effectively promote the scientific and standardized management of laboratory system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
