| 摘 要： | 在基桩施工过程中,判明桩端3倍桩径深度范围内,灰岩岩体内是否隐伏溶洞等不良地质情况,进而决定是否终孔、浇灌基桩,具有重要的现实意义。作者以地震反射波法为理论基础,以单发单收地震勘探和基桩检测技术作为现场作业方法的基础,并吸取两者对勘探资料的解释经验,扼要介绍了运用该方法对湖南涟钢某工程人工挖孔嵌岩桩的桩端灰岩的检测结果及验证情况。

| Abstract: | During the foundation pile construction, the detection of concealed karst caves and other harmful geological conditions in the limestone body within an area of three times the pile diameter at the pile end is of important practical significance in deciding the ending of the drilling and pouring the foundation pile. With the seismic reflection wave method as the theoretical basis and the single transmitting and single receiving seismic exploration and foundation pile test technique as the in-situ working means, the authors, incorporating the interpretation experience of exploration data, deal in brief with the application of the above technology to the exploration of pile end limestone in a certain construction site and its verification result. The achievements made by the authors provide a valuable method and technique for solving similar problems in future. |
