STUDY ON OPTIMAL ARRANGEMENT METHOD OF MULTI-CIRCLE FROZEN HOLE UNDER ACTION OF LARGE VELOCITY GROUNDWATER

To solve the problem that the frozen wall formed by multi-circle freezing pipes is not easy to be closed under the action of groundwater with high flow rate, in view of the action characteristics of groundwater on the artificial freezing temperature field, it was proposed to optimize the design of the conventional freezing scheme by encrypting the
