针对核桃峪副井冻结深度大、地温高、冻结设计中采用差异冻结方案的特点,采用Ansys数值计算方法对地层温度场的发展情况进行了分析,获得了冻结壁发展的相关规律,为项目顺利实施提供了有利保证。
Aiming at the characteristics of large freezing temperature and high ground temperature in the vice well of the Walnut Valley, the differential freezing scheme was adopted in the freezing design. The development of the formation temperature field was analyzed by Ansys numerical method, and the related laws of the development of the frozen wall were obtained. Implementation provides a favorable guarantee.
