【摘要】 园博园是永定河平原城段沿河生态绿色发展带主要的规划公园之一,也是2013年第九届北京国际园林博览会的举办场所,同时园博园湿地还起到再生水净化入河的作用,但是园博园工程区内有大量分布不明的垃圾坑,使设计工作无法正常开展。为了圈定不明垃圾坑的范围,经现场试验研究,决定采用高密度电法、高密度地震映像法、多道瞬态面波法相结合的手段进行勘探,三种方法相互验证、相互补充,探测效果良好,准确查明了垃圾坑的分布及产状,查清了垃圾坑的主要成分,为设计提供了可靠的数据。综合物探技术在园博园垃圾坑勘察中的成功应用,可为今后城市不明垃圾坑勘察提供参考和借鉴,表明综合物探技术又开拓了新的应用领域,将具有更广阔的发展前景。更多还原

【Abstract】 The park expo garden located in the plain region of Yongding River is one of the major planned parks along the river ecological green zone,which will be the venues of the 9th China(Beijing) International Garden Expo in 2013.At the same time the park expo garden wetland also plays the role in purifying the recycle water for Yongding River.There are a large number of rubbish pits at the engineering field of the park expo garden,which makes the design effort unable to be carried out.In order to delineate the unknown garbage pits,through the field tests and study,the high density resistivity method,high density seismic image method and multichannel transient surface wave method are adopted for the exploration.The said three kinds of methods can verify and complement each other.The detection effects are remarkable.The spatial distribution and occurrence of the garbage pits can be precisely identified,and the main components of the garbage pits can be clearly founded out,which can provide the reliable data for the design.The comprehensive geophysical exploration technique are successfully applied to the survey of the rubbish pits in the park expo garden,which can provide the reference for the survey of the unknown rubbish pits in big cities.It shows that the comprehensive geophysical exploration technique develops new application field and will have more wide development prospects.更多还原
