摘      要：Nearly 1100 fissures have formed on the Hebei Plain in *** the Yellow RiverQinghe River-Zhanghe River shallow buried paleochannel band on the plain,93 ground fissures controlled by paleochannels have developed,of which the Wuyi-Fuping ground fissure is a typical paleochannel-controlled fissure located in Hengshui,Hebei Province,with a total length of 3 km,a dominant strike of NE78°,and nearly upright in the shallow *** surface damage observed in this fissure primarily manifests as beaded pits,and its activity shows distinct segmentation *** the trench profiles,the offset distance of shallow layers remains consistently around 20 cm within the depth range of 0 to-3 *** evident flexure is observed in the strata at depths ranging from-4.5 to-7 *** drilling profile reveals that there is an absence of dislocations in the deeper ***,the shallow seismic physical profiles unveil the presence of underlying faults beneath the study area,underscoring the intricate formation process and genesis mechanism of the Wuyi-Fuping ground ***,the formation and evolution of the Qingling River s paleochannel were shaped by the actions of fault blocks and underlying *** interplay of the regional stress field,fault block movement,and fault activity played pivotal roles in driving the development of this ***,the paleochannel exerts a controlling influence on the development location and severity of the *** pumping,the confined aquifer within the paleochannel undergoes water loss and compression,resulting in the formation of a surface subsidence *** the tensile stress surpasses the soil s tensile strength at the funnel s edge,the soil fractures give rise to a ground ***,large amounts of surface water generated by heavy rainfall and irrigation can cause existing hidden ground fissures to rupture,emerge,and *** paper provides a heretofore generally unknown example,promotes
