摘要
为了准确探测在城市更新过程中遗留下来的地下深埋基桩,通过对基桩物性特征和工程项目特点的分析,采用高密度电法和磁梯度法相结合的综合物探方法对地下埋深5 m以内的基桩进行探测,采用科学布孔方式结合磁梯度法对埋深10 m以下的基桩进行探测实验,并应用测斜仪对孔道偏移情况进行系统分析和校正,达到对深层基桩的准确定位。工程应用证明,根据项目背景,选择合理的综合物探方法,可对不同埋深的深埋基桩进行有效的准确定位探测。
In order to accurately detect the deep underground foundation piles left over from the urban renewal process,physical characteristics of foundation piles and the characteristics of engineering projects were analyzed.The comprehensive method combining high density electric method and magnetic gradient method was used to detect deep buried foundation pile.A variety of drilling methods were used,and the inclinometer was used to correct the change of deep hole channel inclination,so as to achieve the precise positioning of deep foundation pile.Through engineering application,it is proved that the method combining comprehensive geophysical exploration and scientific exploration can locate and detect the deep buried foundation pile accurately and effectively.
