| Abstract: | Foundation underpinning is the most economical and safe construction method when subway passing beneath through buildings. In Guangzhou railway transportation line No. 3, some construction techniques, such as dynamically loaded piled foundation underpinning and micro vibration controlled blasting in excavation, were developed to protect the existing adjacent buildings and keep the existing transportation line running safely. |
