摘要
Abstract
In the exploration of Wangjihu stabling yard of Shenzhen Metro Line 8,it was found that there are marble interlayer in tuffolava and the development of karst.The karst caves developed in tuffolava are mainly controlled by weathering layer,fault structure and the spatial distribution of marble interlayer.Wangjihu stabling yard and the surrounding area generally belong to weakly developed karst area,but some local areas belong to strongly developed karst area.The cave sizes are small,the cave 0.80-12.0 m height,average 4.2 m.Karst is mainly developed in the marble interlayer between soil-like strongly and slightly weathered tuffolava.According to the cave sizes,properties of fillings and relationship between karst cave and tunnel,measures such as grouting reinforcement,applying umbrella arch and advanced pipe shed are adopted to ensure the construction quality of pile foundation,safety of tunnel construction and stability of stabling yard.关键词
