Statistical Analysis of Influence of Temperature and Humidity on the Test Results of Plastic Drainage Board

Abstract

Plastic drainage boards are widely used as the most common drainage material in soft foundation reinforcement. The quality of plastic drainage boards directly affects the effect of soft foundation reinforcement. In order to study the influence of temperature and relative humidity on the test of plastic drainage board, the effects of state adjustment and ambient temperature and humidity on the test results were studied by using the method of mathematical statistics. By changing the temperature and humidity in the general indoor temperature and humidity range, and ensuring that the temperature and humidity in the test is consistent with the state adjustment, the plastic drainage board was tested, and the characteristics of data discreteness and the variation of numerical value with temperature and humidity were obtained through statistical analysis. The results show that temperature and humidity have little effect on the width of plastic drainage plate, but have an influence on the numerical size and discreteness of tensile strength and elongation test results. At $180^{\circ}\mathbf{C}$, the tensile strength and elongation of plastic drainage plate complex and the elongation of membrane have great data dispersion.
