【摘要】 对施工区钻孔勘探发现该区域地层复杂,存在大量卵石及其它坚硬岩石,这对顶管掘进会造成很大影响,需要为顶管施工选择合适、有效的施工场址,降低卡钻概率。采用高密度电法技术勘探设备对施工区地层进行详细的勘测,首先对施工区域附近断崖层进行测量,对比剖面反演图分析,证明了高密度电法技术在对地层分布、岩层产状勘探解释上的可靠性,最后采用温纳装置和斯伦贝格装置分别对拟施工区域进行勘测并取得了较好的效果,初步为顶管施工拟定了一条卵石分布较少、卡钻概率较低的地下埋深走向,也减少了钻孔勘探量。更多还原

【Abstract】 Drilling exploration show that the construction area is complex. There are a lot of pebbles and other hard rock,which will have a great impact on the jacking of the pipe jacking. It is necessary to formulate a suitable and effective construction site for the pipe jacking construction and reduce the probability of stuck drilling. The high-density electrical method exploration equipment is used to carry out detailed surveys of the strata in the construction area. Firstly,the fault layer near the construction area is measured,which proves the reliability of high-density electric method technology in the exploration of stratum distribution and rock formation. Finally,The Wenner device and the Schlumberger device are used to survey the proposed construction area and good results are achieved. Initially,a grounding depth trend with less obstacles is proposed for the pipe jacking construction.更多还原
