摘要
具体介绍了砼强度检测抽样的几种方法:现行规程抽样法;简单随机抽样法;分层抽样法．分层抽样 法又分一般方式分层抽样,比例分配分层抽样,及最优分配和奈曼分配分层抽样．在理论上得到各方法的 抽样数量值的基础上,发展了一个混凝土强度检测抽样系统．软件采用Microsoft Visual Basic 6．0编制,软件 应用简单、方便快捷,并通过实例介绍软件的使用方法．
This paper introduced several methods about the concrete strength inspection: the sampling method given by the present specification; simple random sampling without replacement; stratified sampling . The stratified sampling contains common method sampling, proportional distribution sampling, optimum distribution sampling, and Neyman distribution. Based on that the theoretical method, the sampling system for concrete evaluation are developed in this paper using VB 6.0. The software is user -friendly designed and illustrated by several examples.
