大吨位基桩抗拔静载试验的关键实施技术分析

The Construction Technology Research of High-rise Residential Sloping Roof Cantilevered Cornice Structure

随着经济建设的发展,大型建筑物对桩基抗拔承载力的要求越来越高,加载反力装置的问题一直是大吨位基桩抗拔试验的关键技术难题,本文将对大吨位基桩抗拔静载试验的支墩地基处理技术、控制反力支座荷载对荷载及位移的测量影响量的实施技术等进行探讨。

With the development of economic construction,the requirements of the foundation pile anti-pulling static load capacity of large buildings are getting higher and higher.Load reaction force device is always the key technical problems of the large tonnage foundation pile anti-pulling static load test.This paper discusses the buttress processing technology of the large tonnage foundation pile anti-pulling static load test and implement technology to control the influence quantity of reaction force bearing load on the load and displacement measurement.
