膨胀土挖方渠道预支护多排微型抗滑桩设计
Design of pre-supported micro anti-sliding piles with multi-rows for excavated expansive soil canal
摘要
Abstract
Through studying the slope sliding characteristics of excavated expansive soil canal of Middle Route Project of South-to-North Water Diversion, we propose a new canal slope reinforcement measures using micro anti-slide piles that are charac-terized as pre-supported and multi-rows. The pile construction is carried out in parallel with canal excavation and multi-rows of piles are designed to provide graded anti-slide force. In the construction, when excavating to the elevation of the pile, the pile is impressed into the foundation by static pile-driving machine before the next excavation. The new supporting measure has been applied to the canal slope reinforcement of Middle Route Project of South-to-North Water Diversion, and the monitoring results show that the deformation of canal slope is in a stable state, so the reinforcement method is reliable.关键词
