Abstract
Geotechnical engineering investigation is a response to the main purpose of the geotechnical engineering construction site conditions, analysis of engineering problems that may exist, and to make recommendations to resolve these problems and methods. At the same time, evaluation of site conditions for construction projects, such as the safe operation and provide a reliable geological basis. The design of the main love - Zhengzhou Gas Pipeline Project through South-North Water Transfer project trunk geotechnical investigation and site works for the geological evaluation of geological conditions. At the same time, combining their knowledge at this stage and from all the relevant information collected, the project method can be suggested. Obtained as a result of this survey data is limited, therefore the content of this relatively simple design, its main contents include: (1) understand the site's topography and geological structure, the identification of the existence of adverse geological phenomena; (2) understanding through the soil layer characteristics, the thickness variation and the underlying structure, the physical properties of soil and bearing capacity of soil to make the evaluation; (3) understanding of the burial ground water through the paragraph and distribution, and to evaluate the corrosion of underground water; (4) to determine soil category and site type, the evaluation of seismic site effects; (5) evaluation of the stability across the site, especially the stability of the riverbed and banks; (6) proposed a reasonable horizon crossing; (7) proposed methods of construction, and simple understanding of the pipeline projects through the construction of
