广州京溪全埋式污水处理厂抗浮锚杆变刚度设计分析

摘要

By introducing design of anti-floating anchor in Guangzhou Jinxi Underground Sewage Treatment Plant, a variable stiffness design method taking into account of the interaction between the anti-floating anchor and the base slab is proposed for anchor arrangement of large underground structure. This method based on the stiffness distribution of the large basement structure to lay out the anchors in order to increase the anchoring force of anchors , and reduce the base slab displacement and the bending moment. It is a cost-effective method in engineering.%本文通过对广州京溪全埋式地下污水处理厂抗浮锚杆设计的介绍，提出大型地下式结构抗浮锚杆布置时考虑锚杆与底板共同作用的变刚度设计方法，从而根据大型地下式结构的刚度分布有针对性地布置锚杆，使更多的锚杆发挥其抗浮作用，减小底板结构的位移和弯矩，可有效节约工程费用。
