This discipline is called "geoengineering", "geotechnical engineering" or "soil engineering" in some foreign countries and regions. Geotechnical engineering construction is an important part of civil engineering. According to statistics, it includes geotechnical engineering construction survey, design, testing, construction and monitoring, involving the whole process of engineering construction. It is of great significance in various constructions such as housing, municipal administration, energy, water conservancy, roads, shipping, mining, national defense, etc.
