The jet grouting technique was originally initiated in the UK and progressively developed
following the needs for larger geometries, ease of implementation, economic rationality, and …

This paper reviews the material properties of the seal gaskets of shield tunnels. In order to
understand the function of sealing gaskets, the significance and structure of gaskets in …

This paper proposed a series of simple equations to calculate the head difference at the two
sides of waterproof curtain. The barrier effect of waterproof curtain is considered from two …

For deep excavation pits that require the pumping of confined groundwater, a combination of
a retaining wall and dewatering with large-diameter wells is usually adopted during …

Dewatering using a combination of waterproof curtain and pumping wells is commonly
adopted to ensure the stability of foundation pits in multi-aquifer strata. However, dewatering …

It has been observed that in the urban center of Shanghai, land subsidence has accelerated,
and the groundwater level has continued to drop even though the net withdrawn volume …

Waterproof curtains are used as barriers to block groundwater during deep excavations;
however, in practice, barrier leakage occurs frequently. This paper establishes a three …

There exist some difficulties in determining aquifer parameters based on pumping test data
within a partially penetrated retaining walls using traditional Cooper-Jacob method. Many …

This paper presents a case history of geological hazards and treatment measures during the
shield tunneling of Metro Line No. 7, in water-rich mylonitic faults in Guangzhou, China. The …

Recycled glass (RG) is a demolition waste, rich in silica and with a high shear strength and
has been used as a replacement material for sand in various construction applications …
