| 摘 要： | 西安市地面沉降和地裂缝在空间分布上有明显的一致性 ,它们的发展过程和强度变化在时间上也有明显的同步性。诱发地面沉降的主因是过量开采承压水导致承压水位下降 ,含水层介质的孔隙压力减小 ,黏性土层释水压密导致地面永久性的沉降 ,而且浅层的释水压密量大于深层 ;不均匀的地面沉降又诱发了地裂缝。无论是地热井水位或热水开采量的变化 ,还是分层沉降量的观测资料都表明 ,目前西安市深层热水开采还没有加剧西安市的地面沉降和地裂缝活动。控制并减少承压水的开采量 ,是减弱西安市地面沉降和地裂缝活动的最有效的方法 |
| 关 键 词： | 热水 承压水 开采 地面沉降 地裂缝 |

| Abstract: | Xi an region is a geothermal anomaly zone. The geothermal exploitation in this region began in 1990, and has sped up since 1993. At present, there are 120 geothermal water wells with a depth of greater than 1 000m in this region, and this number is still increasing at a rate of 5 to 10 wells per year. Ground subsidence and ground fissures are two natural calamities peculiar to Xi an City. They are famous for long standing formation time, a vast involved range and causing the serious damage of a great numbe |
| Keywords: | Geothermal water exploitation Confined water Ground subsidence Ground fissures |
