摘要

在重质土壤中，湿度的变化会引起土壤体积的变化。在水平面上，这些表现为裂缝的形成，在垂直平面上表现为土壤表面的运动。裂缝对土体剖面的水动力特性有重要影响。这项工作是基于这样一个假设，即土壤体积的变化取决于土壤中粘土颗粒的含量和土壤体积水分。这项工作的目的是测量和分析裂缝宽度的变化及其对土壤体积湿度变化的反应。本研究的目标之一是设计一种简单的工具来精确测量和计算土壤表面的裂缝宽度。为了研究裂缝宽度，选取了东斯洛伐克低地某地区的土壤剖面。该剖面是在2022年7月和8月交替的极端干旱条件下进行的。裂缝宽度在1.0 ~ 3.3 cm之间。计算结果表明，该方法能较好地反映土体表面裂缝宽度的变化情况。

Changes in crack width on the surface of heavy soils during drought, determined by precise measurement and calculation

Abstract In heavy soils, changes in humidity incur soil volume changes. In the horizontal plane, these are manifested by cracks formation and in the vertical plane by the movement of the soil surface. Cracks have a significant impact on hydrodynamics of the soil profile. The work is based on the hypothesis that soil volume changes depend on both the content of clay particles in soil and soil volumetric moisture. The aim of the work is to measure and analyze the changes in the width of the cracks and their reaction to the changes in volumetric soil moisture. One of the objectives of the work was to design a simple tool for accurate measurement and calculation of the crack width on the soil surface. For the study of crack width, a soil profile in an area on the East Slovakia Lowland was selected. The profile was examined under conditions of extreme drought, at the turn of July and August 2022. Crack width varied between 1.0 cm and 3.3 cm. The calculation procedure was evaluated as satisfactory for estimating the change in crack width on the soil surface.

期刊介绍： JOURNAL OF HYDROLOGY AND HYDROMECHANICS is an international open access journal for the basic disciplines of water sciences. The scope of hydrology is limited to biohydrology, catchment hydrology and vadose zone hydrology, primarily of temperate zone. The hydromechanics covers theoretical, experimental and computational hydraulics and fluid mechanics in various fields, two- and multiphase flows, including non-Newtonian flow, and new frontiers in hydraulics. The journal is published quarterly in English. The types of contribution include: research and review articles, short communications and technical notes. The articles have been thoroughly peer reviewed by international specialists and promoted to researchers working in the same field.
