摘要
抗浮锚杆在鹅卵石地层施工中存在钻孔进尺难的问题,从而限制了其在鹅卵石地层的应用。本文结合鹅卵石地层典型工况,运用FLAC3D对原锚杆布设方案开展数值模拟试验,分析地下室底板在地下水、上部荷载和锚杆共同作用下的上浮情况,提出抗浮锚杆优化设计方案并应用于工程现场,使工程顺利进行,为抗浮锚杆在鹅卵石地层的设计与应用提供参考和依据。
In cobble stratum, the anti-floating anchor is difficult to drill, which limits its application.Combined with cobble stratum typical working conditions, the numerical simulation test on the original anchor layout scheme was carried out by FLAC3D.The results of the basement floor floating under the joint action of groundwater, the upper load and the rock bolt was analyzed The design scheme was also applied to the project site to make the project proceed smoothly, which provided reference and basis for the design and application of the anti-floating anchor in the cobble stratum.
