TL;DR: In this paper, the effect of construction on the earth pressures around HDPE pipes buried in fine-grained backfills has not been well understood, and two empirical equations were proposed, based on the numerical results, for predicting the earth pressure at the top and the springline of the pipes during the construction phase.

TL;DR: The ongoing Changi East Reclamation Project in Singapore consists of land reclamation and ground improvement works of the foreshore for the future expansion of the Changi International airport and associated facilities as discussed by the authors.

TL;DR: In this paper, the authors present an analysis of a tunnel failure accident during shield tunnel construction on Foshan Metro Line 2 in China, which is caused by the leakage of the multilayer seal system, which consists of several brush seals at the tail of the shield.

TL;DR: In this paper, the interface shear strength properties of geogrid reinforced recycled foamed glass (FG) were determined using a large-scale direct shear test (DST) apparatus.

TL;DR: In this article, the authors proposed three compression indices for ultra-soft soil with large strain deformation under one-dimensional compression with little or no gain in effective stress, which does not comply with Terzaghi's effective stress gain theory.
