Abstract: Construction of a subway station in Shanghai called for a 31.4–33.1–m-deep excavation, which extended through upper impermeable clayey strata into underlying erodible silt and sand aquifer layers. When the north section ...

Abstract: Any deficiency in excavation design or construction could lead to excessively large retaining wall and ground displacements, usually accompanied by damage to adjacent structures or facilities. This paper documents a case ...

Abstract: The failure of Shanghai Metro Line 4 in 2003 was one of the most striking accidents in the history of subway construction in China. It involved the first breach failure of a cross passage being mined by an artificial ...

Abstract: This paper presents the results of statistical analyses on a database comprising 592 deep excavations in Shanghai soft clays from 1995 to 2018. First, the general trends and patterns over time are outlined for seven different ...

Abstract: With an inclinometer casing mounted on a sheet pile wall in peat bogs, sheet pile wall deflections were measured during a trial deep dynamic compaction (DDC) test. Analyses of the trial testing data indicated that sheet ...

Abstract: To date, cases of severe ground subsidence or abrupt cave-in failure of roadway without warning after crushing and removing boulders in the sand matrix by tunneling have been frequently reported in practice, which jeopardize ...

Abstract: This paper investigates the effectiveness of open trenches in reducing the deflections of sheet pile walls during deep dynamic compaction (DDC). This investigation included a series of comprehensive parametric studies using ...

Abstract: This paper investigates bolted sleeve joints for connecting tubular pultruded fiber-reinforced polymer (FRP) sections in tubular structures such as space frames. In the proposed joint, FRP profile and steel connector are ...
