1 引言高层框架结构的荷载集中柱底,压力大,在一些深填土但下部土质较好的地方,较适宜采用大直径挖孔扩底灌注桩。大直径挖孔扩底灌注桩具有施工迅速、安全、可靠、经济,适合各类复杂土层等优点。本文将着重通过介绍在郑州市中原区检察技术中心办公楼设计中所遇到的实际情况,来分析大直径挖孔扩底灌注桩设计中应注意的问题及桩身构造设计。
1 INTRODUCTION The load of the high-rise frame structure is concentrated on the bottom of the column, and the pressure is large. In some deep-fill but lower soil, it is more suitable to use the large-diameter digging hole expanded bottom pouring pile. Large diameter digging holes expanded bottom pouring pile with rapid construction, safety, reliability, economy, suitable for all kinds of complex soil and other advantages. This article will focus on introducing the actual situation encountered in the design of office building of Procurator & Commissar Technology Center in Zhongyuan District of Zhengzhou City to analyze the problems that should be paid attention to and design of pile structure in the design of large diameter bored and expanded bottom bored pile.
