Majalah Konstruksi, Nomor 188, Desember 1993

Pembangunan gedung yang kian tinggi dengan besmen yang makin dalam, merupakan tren yang ditemui pada kota-kota besar, seperti Jakarta. Dari aspek engineering tuntutan persyaratan teknisnya kian tinggi. Di sisi lain, para investor juga menghendaki biaya investasi yang seefisien mungkin. Bagaimana struktur gedung yang kian canggih itu tetap aman, sementara biaya yang dikeluarkannya harus optimal, merupakan tantangan yang perlu dijawab oleh para perencana, termasuk seorang geotechnical engineer.

ABSTRACT: The writer has been working in the field of geotechnical engineering since 1984, along the way he has seen a number of deep excavation failures, some with minor casualties, others involving a huge amount of economic loss, some cost no human life, others with a number of fatalities. One recent major failure was the failure of a cut and cover tunnel deep excavation in our neighboring country which has cost not only a huge financial of loss, but also cost four human life. This paper tries to discuss what can be learned from those failures. It also discusses the possible technical and the non technical reasons, such as: the lowest bid win policy.

Notes on The Application of Spring Constant and Soil Structure Interaction Problem

Written by Gouw Tjie Liong, Ir., M.Eng, ChFC, PhD. Posted in GTL Paper

ABSTRACT: Despite the advancement of the computer technology and engineering software, which allows soilstructure interaction to be analyzed economically, the concept of spring constant is still widely used inanalyzing raft and pile raft foundation. This paper first reviews the spring constant concept, itslimitation and the misused of the value in evaluating building foundation. Finally, a case study on abuilding, soil and tunnels interaction is given as an example of solving a soil structure interactionproblem by using geotechnical finite element software.
