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
