摘　　要：通过室内土工试验和现场原位测试,对一基坑事故前后的岩土工程环境变化、岩土体参数变异进行了对比研究,结果表明现场勘察数据具有时效性,在基坑工程方案设计时应予以考虑,以避免类似事故的发生。Based on the soil test both in lab and in-situ, a comparative study was made on the environmental change in geotechnical engineering and parameter difference in rock-soil mass before and after a foundation pit accident. Results show that the timeliness of on-site exploration data should be taken into account during foundation pit engineering design, so as to prevent such accident happening again.
