摘要
入岩判断是钻孔嵌岩桩施工过程中的质量控制重点,根据勘察钻孔与桩位的相邻关系预估桩长是常用的方法之一。为了提高桩长预估的效率和精度,以克里格空间插值法和Arc GIS软件批量赋值功能为基础,提出一种基于钻孔信息的嵌岩桩桩长推演方法,并通过某高填方嵌岩桩灌注桩施工项目的实践,证明该方法的有效性,可为类似工程提供借鉴。
The judgement of drilling into the rock is the key part of the quality control during the process of rocksocketed pile construction. One of the commonly used method to forecast pile length is by according to adjacent relationship of the survey hole and the pile site. In order to improve the precision and efficiency of pile length estimation,a method of rock-socketed pile length deduction according to the information of borehole is put forward in this paper,which based on kriging interpolation method and the function of batch assignment of Arc GIS software.The effectiveness of the method is confirmed through the practice of rock-socketed pile construction in a high filled project. And it provides a reference for the similar projects.
