| 摘 要： | 静力触探技术(CPT)具勘探和测试双重功能,在地基处理方面应用广泛。以中东某液化天然气进口(LNGI)工程吹填砂场地地基处理为例,根据工程的勘察、设计、施工不同阶段,分析了静力触探技术在回填场地土层分类、地基处理验收曲线确立、CPT-SPT关系建立、吹填料的质量监控、地基处理质量的检测验收中的应用。该吹填砂地基处理的监测与检测思路、方法可供类似海外高标准地基处理借鉴。

| Abstract: | Cone penetration test (CPT)has dual functions of site investigation and assessment,and is widely used in soil improvement.Taking the ground improvement of a LNGI project in the Middle East as an example,CPT technology is widely applied in different stages,such as investigation,design and construction.The paper analyses CPT application to soil layer classification,performance curve establishment,CPT-SPT relationship determination,quality controling of backfill and inspection of ground improvement.These ideas and scheme shall provide meaning reference for silimar project design and construction especially overseas projecte. |

| Keywords: | cone penetration test hydraulic fill sand ground groud improvement inspection target performance curve |
