摘要: 获取准确的土体力学参数,是工程勘察的主要目的之一。原位测试技术能够在尽可能避免对土体结构造成扰动、不释放土中应力的条件下,获取土体的各项参数,且效率和成果精度高,在岩土工程领域应用前景广阔,自钻式旁压试验是其中的佼佼者。依托孟加拉帕德玛公铁两用大桥工程勘察项目,引进了国外先进的原位测试设备,在实际工程中通过大量应用和设备、技术改进,为项目获取了准确可靠的土体参数,并在工程实践中推广和应用自钻式旁压试验起到了积极推动作用。

Abstract: It is the main purpose to obtain accurate mechanical parameters and appraise the mechanical properties of the soil and to provide reliable basis in the engineering investigation planning. The in-situ testing technology can obtain various parameters of the soil without releasing the pressure in the soil and disturbance to the soil structure. It has a high efficiency and precision, so it is increasingly popular and has a wide application in the geotechnical field. The self-boring pressurementer test is one of the most widely tests. Based on the investigation project of the Padma Multipurpose Bridge in Bangladesh, the accurate and reliable soil parameters for the project by the introduction and improvements of the foreign advanced insitu testing instruments are obtained. These efforts made a positive contribution to the promotion and application of the self-boring pressuremeter test.

Key words: Self-Bored Pressuremeter Test, InSitu Test, Engineering Investigations
