摘要
系统分析了广州市金沙中学地面沉降的成因,研究结果表明,金沙中学脆弱的地质环境条件是该地区地面沉降地质灾害频发的内在因素,而武广客运专线金沙洲段隧道施工等人类工程活动是诱发因素。建议今后工程项目选地尽量避免地质环境脆弱带,并严禁过量抽排地下水。
Systematic analysis of the causes of ground subsidence in Jinsha high school was studied based on the field survey. Results showed that fragile geological environmental conditions in Jinsha high school is the internal factor results to ground subsidence and human engineering activities of the Wuhan-Guangzhou high-speed rail tunnel excessive pum- ping of groundwater is a predisposing factor. Finally, the corresponding countermeasures and suggestions were discussed for prevention and control of geological hazard.
