高层建筑深基坑锚杆、土钉墙设计

Design of Roofbolts and Soil Nailings for Deep Foundation Pits of High-rise Buildings

文章综合某高层建筑基坑锚杆、土钉墙实践,介绍在上层滞水水位较低,地层渗透系数大的水文地质条件下,基坑锚杆、土钉墙技术参数选取、方案设计等过程。监测结果证明,此项工程的锚杆、土钉墙方案设计合理,技术参数选取正确,对同类工程有指导意义。

In the paper,it is introduced the processes such as selecting technical parameters and schematic design for roofbolts of foundation pits and soil nailings with the hydrogeological conditions of lower perched water level and big osmotic coefficient of stratum.The results of monitoring show that the schematic design for roofbolts and soil nailings of the project is reasonable as well as the selection of technical parameters is right,which could provide significant references for the similar projects.
