摘要
介绍了侧向千斤顶式取样器设计计算、工作原理、使用注意事项。取直径２００ｍｍ大坝混凝土与基岩胶结面样，取样时保证胶结面在不受力的条件下，在孔口操作千斤顶，使它产生水平推力，最终推断岩心并取出。
Abstract The design calculation and operating principle of the side jack sampler are described with some notes in its use. For taking a 200 mm core from the binding surface between the dam concrete and the bedrock with the binding surface free of the action of forces, the jack was operated at the hole collar to produce a horizontal force to push broken the core at length and take it out. side jack, sampler, core, horizontal thrust
