Abstract

The sheet pile bracing system is the most well-known for excavation work in Bangkok soft marine clay. The sheet pile wall which is defined as flexible wall will show a large significant of lateral deformation and ground surface settlement if the excavation system is carried out without a good quality control. The sheet pile bracing system with fully effective preloading strut system was designed for basement excavation of 11.3 m. deep of Bai Yok Tower II. The results indicate that berm width can reduce the maximum sheet pile wall deflection only at the first three stages of excavation. The fully effective preloading strut system tend to show the lower measured wall deflection ratio against basal heave than those proposed by Mana & Clough (1981). The prediction of maximum wall deflection by simplified method proposed by Wong & Brom (1989) agree well with the field measurement only at the final stage of excavation.

Behavior of Deep Excavations Using Sheet Pile Bracing System in Soft Bangkok Clay

St. Louis, Missouri

The sheet pile bracing system is the most well-known for excavation work in Bangkok soft marine clay. The sheet pile wall which is defined as flexible wall will show a large significant of lateral deformation and ground surface settlement if the excavation system is carried out without a good quality control. The sheet pile bracing system with fully effective preloading strut system was designed for basement excavation of 11.3 m. deep of Bai Yok Tower II. The results indicate that berm width can reduce the maximum sheet pile wall deflection only at the first three stages of excavation. The fully effective preloading strut system tend to show the lower measured wall deflection ratio against basal heave than those proposed by Mana & Clough (1981).
