对阻沙工程中普遍应用的立式沙障立柱受力及其埋深进行了分析与计算，使阻沙工程措施的立式沙障埋深由过去的经验确定转为计算确定，避免了盲目性；确定立式沙障有效高度１ｍ，在复合沙障阻固结合防沙工程中，是一种集阻沙和导沙于一体的很有价值的防沙工程。计算对于确定立式沙障的结构、材料用量，提高工程的稳定性方面具有重要的参考价值，为阻沙工程设计和施工提供了科学的依据
This paper analyzes and calculates the stress and vertical depth of the vertical sand barrier bar commonly used in the sand block project so that the vertical sand barrier depth of the sand barrier engineering measures is changed from the past experience determination to the calculation and determination and the blind The effective height of vertical sand barrier is 1m. It is a valuable anti-sands project that integrates the functions of sand-blocking and sand-guiding in the combination of sand barrier and sand control. The calculation has important reference value for determining the structure of the vertical sand barrier, the amount of material used and the stability of the project, and provides a scientific basis for the design and construction of the sand-blocking project
