摘　　要：探索分析引入盾构技术直接开发利用基础地热能的可行性。地热梯度及地热资源的分布特点揭示,只要有足够的深度就能获得足够的地温。传统的地热勘查和地热开发技术受到多种因素制约,使地热资源的开发利用受到了极大的限制,引入盾构技术开发利用深部基础地热资源,将是一种颠覆性和革命性的地热开发技术。本文通过分析地热资源的分布特征,结合盾构技术的特点,探索一种广泛利用基础地热能的技术、方法和可能性。This paper mainly studies the feasibility of development and utilization of basic geothermal energy by shield tunneling technology.According to the geothermal gradient and distribution characteristics of geothermal resources,it reveals that enough geothermal energy can be obtained as long as enough depth.Traditional geothermal exploration and development technology is restricted by many factors,limiting the development and utilization of geothermal resources.It will be a revolutionary technology for introducing shield technology to develop and utilize deep geothermal resources.This paper attempts to study the possibility of wide utilization of basic geothermal energy on the basis of distribution characteristics of geothermal resources,the technical characteristics and application status of shield tunneling.
