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 …

The Quaternary soft deposits of Shanghai form a multi-aquifer–aquitard system (MAAS) with
aquitards of high compressibility and aquifers of high groundwater table. The metro tunnels …

This study presents an improved trapezoidal fuzzy analytic hierarchy process (FAHP) to
assess the risk of mega-city infrastructures related to land subsidence. The trapezoidal fuzzy …

This paper provides a straightforward way to evaluate tunnel settlement caused by land
subsidence in the soft deposits of Shanghai. By analyzing field measurements of tunnel …

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 pum** 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 pum** wells is commonly
adopted to ensure the stability of foundation pits in multi-aquifer strata. However, dewatering …

This paper presents a case history of the successful application of observational method to
instruction microtunneling with successive pipe-jacking. The microtunneling project is the …

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and the groundwater level has continued to drop even though the net withdrawn volume …
