This paper performs an extensive literature survey and example investigation on the stabilisation of slurry wall trenches during the construction of diaphragm wall panel trenches, and the failure modes of slurry wall trench instability, the stability theoretical analysis models and methods, the slurry formation and its protection mechanism, the influence of related factors on slurry wall trench stabilisation, and other related problems are summarized and analyzed emphatically. And then, based on the limit equilibrium analysis method, the mechanical models of the overall stability and local stability of the trench wall are established, respectively, and the design method of slurry unit weight is derived to ensure the stability of the trench wall. Furthermore, an example application shows that the established slurry unit weight design method is reliable. At last, this paper also proposes the focus and direction for follow-up work, that is, to construct an accurate and effective theoretical analysis model of slurry wall trench instability considering the influence of multiple factors and the calculation method of the slurry cake and its mechanical or mathematical relationship with slurry quality. Diaphragm wall panel trenches are continuous underground walls with seepage proof, waterproof, and retaining and bearing functions that are formed by using digging machines to excavate narrow and deep grooves underground and pour materials inside with the help of a slurry wall [ 1 ]. Originated from Europe, the diaphragm wall panel trench excavation technology has been developed using the slurry and underwater concreting method for oil drilling [ 2 ].

This paper presents the construction performance of an internally braced diaphragm wall constructed by the slurry trench method at a waterfront site on the Boston Harbor in Massachusetts. Due to the proximity of an existing building, waterfront structures and the harbor, as well as the unfavorable subsoil conditions, a cross-lot bracing system was selected for excavation support. The earth support system was instrumented by inclinometers and strain gages, and the existing abutting building was monitored by settlement reference points. Instrumentation data allowed monitoring of performance of the excavation support system as well as settlements in the existing adjacent building during the foundation construction. The performance data indicated significantly unsymmetrical lateral displacements of the opposite diaphragm walls resulting from the unequal loads imposed by the building surcharge on one side as well as the limited soil mass on the opposite harbor side. Also, the daily collected data made it possible to take quick remedial action on the lateral support system at the time of a critical incident.

Janssen Published Engineering Both a circular slip surface stability calculation Bishop or Fellenius and a Finite Element Method calculation c-phi reduction produce a safety factor but not a probability of failure or reliability index. A Monte-Carlo method leads, because of the many slip surface calculations, to the most accurate calculation of the probability of safety, but this method is far too time consuming for daily FEM calculations.
