本文将置信估计理论和误差传递理论用于预估岩土设计参数,建议了一种可行的实用方法。用该法预估岩土参数较之确定方法更为合理,可将工程费用与钻探取样试验的数量、质量联系起来,使经验公式的实用价值与研究工作的深度与广度联系起来。在此基础上可以进一步建立技术与经济两个方面之间的联系。 In this paper, the confidence estimation theory and error transfer theory are used to estimate the geotechnical design parameters, and a feasible practical method is proposed. Using this method to estimate the geotechnical parameters is more reasonable than the determination method. It can link the project cost with the quantity and quality of the drilling sampling test, and link the practical value of the empirical formula with the depth and breadth of the research work. Based on this, we can further establish the links between the two aspects of technology and economy.
