摘要
由《岩土锚杆与喷射混凝土支护工程技术规范》(GB 50086-2015)中关于抗浮锚杆整体抗浮稳定验算的规定可知,抗浮锚杆整体稳定性与基础下抗浮锚杆范围内总的土体重(W)、结构自重和其他永久荷载(G)及地下水浮力(Ff)有关,结构自重和其他永久荷载(G)及地下水浮力(Ff)可通过相关规定计算得出,但规范并未给出抗浮锚杆范围内土体重(W)的计算方法.对抗浮锚杆的受力情况进行了分析,参照相关规范,通过理论推导,提出了抗浮锚杆整体抗浮稳定验算的计算公式.
Abstract
According to the technical code for geotechnical bolt and shotcrete support engineering(GB 50086-2015),the checking calculation of anti-floating stability of anti-floating bolt as a whole can be known,the overall stability of the anti-floating an-chor was related to the total weight of the soil(W),the self-weight of the structure,other permanent loads(G)and the buoyancy of the groundwater(Ff)in the scope of the anti-floating anchor under the foundation,the self-weight and other permanent loads(G)of the structure and the buoyancy of the groundwater(Ff)can be calculated by relevant regulations.The stress of the anti-floating anchor was analyzed,and the calculation formula of anti-floating stability checking of the anti-floating anchor was put forward according to the rel-evant codes.
