Abstract
Geotechnical aspects in construction of diaphragm-wall-support 2 level underground car park building, located in the historically and culturally significant area of Bangkok is presented in this paper. Results of the preliminary analyses showed that the deflection of the thin diaphragm wall of 0.60 m width would be large if it was to be fully cantilevered to fulfill the architectural and utility aspects of the car park structure. It was therefore decided to use buttress to minimize the diaphragm wall deflection. Performance of buttressed-support diaphragm wall is demonstrated based on the inclinometer monitoring results. Intensive modification of construction sequence in actual work execution with “value engineering options” different from tender stage design is demonstrated along with application of observational method.
