| Abstract | Field Monitoring and In-Situ Tests were carried out t o evaluate the amount of subsidence and subsidence effects in AIT campus. Precision Surface Levelling were done t o observe the absolute subsidence. Inclinometers were installed in NZ housing to observe the horizontal ground movement. The existing compression indicators were monitored to observe the deep and shallow compression. In-situ Tests consisted of Vane Shear tests, Dutch cone tests and Pressuremeter tests were done to find out the in-situ soil properties in upper clay layer down to 10 m depth. The results of Precision Surface Levelling in three months period (December 11, 19 83 to March 3, 1984) were found that the ground surface elevation is about 1.7 to 2.3 m above Mean sea Level, the maximum settlement of ground surface is 2.06 cm occurred near pumping well no. 3 and the average settlement on pavement in the central AIT campus is about 0.5 cm While the settlements of the buildings were found a maximum of 3.94 cm occurred in the servant's quarter NZ Housing no. 1 which directly rest on ground surface. For Academics and Administration building, the maximum settlement were found in damaged walls with the values of 2.5 cm and O. b9 cm , respectively. A maximum of 4.39 cm was measured in the walkway between Hockey and Football Fields, while the Dormitories and Library building registered negligible settlements. The results of the in-situ soil tests such as the pressuremeter tests, the Vane Shear tests, and the Dutch cone tests showed the presence of a thick weaker layer of soft clay of very high compressibility in the subsoil below the Central Campus and NZ Housing area where almost damages occurred. The maximum horizontal ground movements registered in the inclinometers in NZ House no. 3 in three months period was 1.13 cm in the direction of 56.16 degrees with the W-E axis towards the canal. |
