复杂地质条件下地下工程施工支洞动态设计与调整

Dynamic Design and Adjustment of Construction Drifts for Underground Engineering under Complicated Geological Conditions

针对溧阳抽水蓄能电站地质条件复杂的特点,施工支洞布置与设计做到了及时反馈、及时研究、及时调整、及时优化。对该电站地下工程施工支洞动态设计进行了总结,包括施工支洞规划布置、支护形式及断面形式调整等。目前,施工支洞大多均已完成开挖支护,为主体工程顺利开展打下严实基础。

Because of complex geological conditions in Liyang Pumped-storage Power Station, the layout and design of construction drifts is fed back, researched, adjusted and optimized in a timely manner. The dynamic design of construction drifts for the underground engineering of Liyang Pumped-storage Power Station are summarized herein, including the layout, support pattern and section shape of drifts. At present, the excavation and support of most of drifts have been completed and lay a solid foundation for the smooth development of main structures.
