<p>This paper presents a preliminary study on the system reliability for the geotechnical design of braced excavations in soft clays. In this system reliability geotechnical analysis, both ultimate limit state (ULS) and serviceability limit state (SLS) are ...

Nailed-slab System is a proposed alternative solution for rigid pavement problem on soft soils. Equivalent modulus of subgrade reaction (k’) can be used in designing of nailed-slab system. This modular is the cumulative of modulus of subgrade reaction from ...

<p>In this paper, cyclic triaxial loading tests were conducted on specimens of soft clay with varying cyclic stresses and frequencies to investigate the performance of soft soil subgrade subjected to cyclic loading. The laboratory results indicate that given ...

<p>Cone penetration test (CPT) or piezocone penetration test (PCPT or CPTu) has long been used to estimate the undrained shear strength of clays. However,<br />the undrained shear strength itself is not a unique measure of soil strength; different laboratory ...

<p>This paper presents the results of a series of piezoball penetration and<br />dissipation tests carried out at two well characterized soft soil sites in Ireland.<br />Piezoball data are compared with piezocone data, in addition to other in situ and laboratory ...

<p>Deep excavations frequently cause problems, and sometimes trigger catastrophic collapses, especially in soft clay. In principle, these problems are well understood, but designers may fall between the two stools of naive empiricism and overelaborate finite ...

<p>TxDOT frequently uses Texas Cone Penetrometer (TCP) blow counts to estimate undrained shear strength. However, the current correlations between TCP resistance and undrained shear strength have been developed primarily for significantly stronger soils than ...

<p>This paper presents the design, construction and back analysis of the basement retaining wall of a major commercial development in Bogota, Colombia. The development consists of 4 eleven-story office towers, and 4 basements for car parking use, occupying ...

Lateral load tests were performed on a full-scale pile cap in clay before and after construction of eight 1.5 m diameter jet grout columns to a depth of 3 m around the pile group. Jet grouting with a cement content of about 400 kg/m3 (20% by weight)increased ...

<p>The observed response of diaphragm wall and the surface settlement of a deep excavation for a metro station in Shanghai soft clay are presented, compared with the similar excavations (retained by a diaphragm wall) in soft clay areas in Asia and five metro ...
