岩土参数选用计算系统的开发研究

DEVELOPMENT OF CHOICE AND CALCULATION SYSTEM OF CIVIL PARAMETERS

岩土参数是岩土工程设计的基本参数。岩土工程师在完成1项工程前,往往面对的是大量数据,如何处理这些数据进而提出真正反映岩土实际性状的参数,符合岩土工程可靠性的设计要求是1项十分重要的工作。而岩土参数的变化具有很强的地域特征,岩土参数值具有显著的不确定性。对岩土参数值的分布规律进行分析,对其数值进行选用在岩土工程设计中具有重要意义。本文主要应用概率和数理统计的方法对岩土参数的不确定性进行分析评价,获得参数的标准值及参数的修正系数,以便于岩土工程设计参数的正确选择和合理选用,并结合工程实际的特点,运用V isual Basic语言对岩土参数的选用进行程序化设计,方便工程设计应用。

Civil design parameters are the basic parameters. Civil engineers often face a lot of data before a project is completed. In order to reflect truly the actual characters of rock - soil parameters and to conform to the civil engineering design requirements, how to handle these data is a very important work. Because the civil parameters are all with strong geographical features, civil parameters have significant uncertainty. To analysis the civil parameters of distribution of the regular pattern and to select those valuable data in the civil engineering design is of great significance. In this paper, the chief thread is to analyse the uncertainty of civil parameters and assess the civil design parameter~ data on the method of probability and statistics. Standard values of parameters and correction values of parame- ters are got, which is served to determination and right choice of the parameters in civil engineering design. On the basis of actual engi- neering characteristics, a system is developed for the selection of the civil parameters which facilitates the application.
