Research on Soil Strength Determination Method Based on Moisture Content and Porosity Ratio

摘要: 黄土灾害对于黄土高原地区的生态地质环境和人民居住安全构成了严重威胁。黄土具有的特殊细观结构特征，是造成黄土灾害的根本原因。黄土的细观结构随着外界环境的改变在不断地演变，这对其宏观力学行为具有决定性影响。本研究旨在探讨一种利用土壤含水率和孔隙比确定土壤强度的方法。通过对不同含水率和孔隙比条件下的土壤样品进行试验，收集数据并进行分析，发现含水率和孔隙比对土壤强度具有显著影响。实验结果表明，随着含水率和孔隙比的增加，土壤的强度逐渐降低。基于这一发现，我们提出了一种简便有效的土壤强度确定方法，可以通过含水率和孔隙比的测量值来预测土壤的强度水平。本研究为土壤工程领域提供了一种新的强度确定途径，具有一定的实用和推广价值。

Abstract: Loess disasters pose a serious threat to the eco-geological environment and people’s living safety in the Loess Plateau. The special mesoscopic structure characteristics of loess are the root cause of loess disasters. The mesostructure of loess is constantly evolving with the change of the external environment, which has a decisive impact on its macroscopic mechanical behavior. The purpose of this study was to explore a method for determining soil strength using soil moisture content and porosity. Through the experiments of soil samples under different conditions of moisture content and porosity ratio, the data were collected and analyzed, and it was found that the moisture content and porosity ratio had a significant effect on soil strength. The experimental results show that the strength of the soil gradually decreases with the increase of moisture content and porosity ratio. Based on this finding, we propose a simple and effective method for determining soil strength, which can predict soil intensity levels from measurements of moisture content and porosity. This study provides a new way to determine the strength in the field of soil engineering, which has certain practical and popularization value.
