青岛奥运演艺大棚利用潮汐差的基础施工工艺

针对抛石区抛石大小不均匀、临海等复杂地质特点,结合青岛奥运演艺大棚工程实例,阐述了避潮作业的关键技术,综合对比分析了旋喷桩止水帷幕及利用潮汐差进行独立基础施工两种方案,提出了科学合理、经济可行的避潮作业方案.实践证明,该方案减少了围护和止水成本,节约了工期,加快了施工进度,适合于抛石区及临海复杂地质条件.

Foundation Construction Technology Based on Tidal Difference in Qingdao Olympic Performance Shed

According to the uneven sizes of ripraps in riprap regions and the complex geological conditions in the vicinity of the coast,and combined with the practice of Qingdao Olympic Performance Shed,this paper expounds the key techniques to avoid tides.It compares and analyses comprehensively the two kinds of schemes of the jet grouting pile sealing curtain and the employment of tidal difference to conduct an independent basis so that a scientific,rational and economical scheme to avoid tides is put forward,which reduces the cost of the envelope and the sealing curtain,shortens the term and speeds up the progress of the project.This scheme is suitable for riprap regions and the complex geological conditions in the vicinity of the coast.
