Abstract: Site stability and suitability evaluation is an important content in geotechnical engineering survey and evaluation. Whether the evaluation conclusion is appropriate or not will have a direct impact on the feasibility and cost of the project, which is not given in the current traffic and water operation industry related regulationsAccording to the corresponding evaluation rules, technical personnel often lack basis when making relevant evaluations, which results in more random evaluation conclusions.This article takes the station building as an example, combined with its engineering characteristics and personal engineering experience, and comprehensively refers to the corresponding regulations of the industry (hydropower, urban and rural planning) and the special project of the station building disaster assessment to determine the stability and suitability of the station building site.The evaluation method is introduced in detail, and the evaluation conclusion will provide a reasonable basis for the subsequent geotechnical engineering evaluation and design, and also provide a reference for colleagues in the transportation, water transport and highway industries in order to obtain a consensus.
