摘要
为提供准确的地质勘察结果,研究基于改进BP算法的岩土地质勘察质量控制技术.该技术以BIM技术为基础,通过建立工程地质体模型,利用该模型输出工程地质体的地质勘察孔平面布置图、地质剖面等信息;再利用地质雷达向地面发射高频电磁波方式得到地质裂隙反射电磁波,并使用改进BP算法以及地质雷达勘察成像方法得到地质体内部形态信息,为建筑施工方提供地质裂隙图像.试验结果表明:该技术获取的地质勘察孔量测点位置较为精准,其生成地质裂隙图像较为清晰完整,且受干扰噪声影响较小;应用该技术后,工程施工地基沉降数值较小,质量控制应用效果较为显著.
Abstract
In order to provide accurate geological survey results,the quality control technology of geo-technical geological survey based on improved BP algorithm is studied.The technology is based on BIM tech-nology.By establishing the engineering geological body model,the model is used to output the geological survey hole layout map,geological section and other information of the engineering geological body.Then,the geological radar is used to transmit high-frequency electromagnetic waves to the ground to obtain the re-flected electromagnetic waves of geological fractures,and the improved BP algorithm and the geological ra-dar survey imaging method are used to obtain the internal morphological information of the geological body,so as to provide the geological fracture image for the construction side.The test results show that the position of the geological survey hole measuring point obtained by this technology is relatively accurate,and the gen-erated geological fracture image is relatively clear and complete,and is less affected by interference noise.After the application of this technology,the settlement value of the construction foundation is small,and the application effect of quality control is more significant.
