extrusion process. Soft-Mud Process - The soft-mud or molded process is particularly suitable for clays containing too much water to be extruded by the stiff-mud process. Clays are mixed to contain 20 to 30 percent water and then formed into brick in molds. To prevent clay from sticking, the molds are lubricated with either

The Modified Cam-Clay properties are shown in Table 1. The soft soil is modeled for a depth of 12 m with varying smear zone ratio and drain ...
This paper describes the monitoring of the construction of a deep underground waste storage bunker for the PROTOS energy-from-waste facility in Chester, UK. A key element of the construction process was a 12 m deep excavation in soft clays and peats which was supported by a complex 'combi-wall' cofferdam comprising alternate tube and sheet piles, a …
This paper presents a novel strut-free earth retaining wall system for excavation in soft clay, referred to as the rigid and fixed diaphragm (RFD) wall retaining system. The RFD system is comprised of four main structures—diaphragm walls, rib-walls, cross walls, and buttress walls—and a complementary structure—the cap-slab. The characteristics of the RFD system …

The soft clay deposit is described by a visco‐hypoplastic constitutive model considering the rheological properties and the small‐strain stiffness of the soil. The construction process considerably affects the effective earth and pore water pressures adjacent to the wall.
In clay soil, excavation-induced stress and deformation in surrounding ground are also influenced by consolidation process and creep. Thus, numerical analysis with effective constitutive law should consider this phenomenon along with stress–strain relationship to predict the surrounding ground behaviour more realistically during excavation.
Reducing the area can speed up the excavation process and the construction of struts for each zone to form a complete retaining system sooner. This is important for projects in soft clay where secondary compression may take a noticeable proportion of wall and ground deformations if the construction lasts for a long period. The excavation ...
The construction of underground space in soft clay is becoming more complex, which brings great threats to construction safety. Taking a deep foundation pit in Suzhou as an example, the deformation of the foundation pit and retaining structure was calculated by FLAC 3D, and the main factors were analyzed. The results show that the simulation results fit the data …

In the older method of forming bricks, the soft-mud process, much more water is used, and the mix is placed in wooden molds to form the size unit desired. To keep the clay from sticking, the molds are lubricated with sand or water; after they are filled, excess clay is struck from the top of the mold.
