Research on Source Material Characteristics and Engineering Prevention and Control Schemes for Debris Flows Around Schools in Mountainous Townships
山区乡镇学校周边泥石流物源特征及工程防控方案研究

摘要

本文主要研究山区乡镇学校周边泥石流灾害给师生安全、财产安全带来的严重危害，对泥石流灾害物源特征进行 解析并提出相应的工程治理措施。以区域地质为基础，从泥石流成因机理、物源空间分布规律、矿物成分性质、储量 特征出发，结合地形地貌和气象因素的相互作用，提出一种以拦挡防护、排泄疏导、坡面治理为一体的防洪减灾技术 方案。该成果可以给有关地区校舍防灾减灾工作给予理论支撑和技术协助。 

Abstract

This paper mainly studies the serious threats posed by debris flow disasters around schools in mountainous townships to the safety of teachers and students as well as property safety. It analyzes the source material characteristics of debris flow disasters and proposes corresponding engineering control measures. Based on regional geological conditions, this paper examines the formation mechanism of debris flows, the spatial distribution patterns of source materials, mineral composition properties, and reserve characteristics. In combination with the interaction between topography, geomorphology, and meteorological factors, a flood prevention and disaster reduction technical scheme integrating blocking protection, drainage and diversion, and slope treatment is proposed. The research findings can provide theoretical support and technical assistance for disaster prevention and reduction work in school buildings in relevant regions.
