Abstract: In recent decades, the geotechnical survey industry has been developinged slowly. The Internet digital platform model was introduced, and sharing platform of engineering geological information was developed, which realized the effective use of geological survey results, promoted the development of the geotechnical engineering experience evaluation system, and enhanced the vitality and efficiency of the engineering geological survey industry. This paper systematically reviews the development of geological information sharing platform and related standards at home and abroad, and summarizes the significance of platform development and the current problems and challenges. The suggestions for the construction ofng the an all-element geological information platform are as follows: (1) Strengthen the exploration of the co-construction and sharing mechanism of all-element geological information; (2) The AGS format is widely used in European and American countries, and it should be introduced to develop data storage and transmission standards; (3) The engineering geological survey industry has long been conservative and closed in thinking, and urgently needs to be more liberatedliberal; (4) Taking in venture capital can effectively guarantee the capital investment for the continuous development of the platform.
