The first 25 years of satellite carbonate sedimentology: What have we learned?

The Depositional Record, EarlyView.
Observations of the suspension and transport of carbonate sediments from reefs, banks and shallow shelves have been made by satellite instruments for ca 25 years. With an increasing number of instruments in space, providing advanced observational capabilities, remarkable insights have been gained concerning carbonate sedimentological processes. Details

Effects of elevated ground temperatures on properties of cement grouts for deep rock grouting

Deep Underground Science and Engineering, EarlyView.
When the temperature is up to 35°C, significant improvement in rheological parameters, acceleration of grout setting, and an increase in the rheological time dependence of thick cement grout can occur, but there may be a slight effect on the initial grout flowability and the nature of shear thinning.

Experimental study on the damage characteristics of cyclic disturbance and acoustic emission characteristics of different types of sandstones under high stress in deep mines

Deep Underground Science and Engineering, EarlyView.
The mechanical characteristics of three different types of sandstones under high stress levels are studied. The degree of fragmentation of specimens increases with the applied stress level. The acoustic emission counting of different types of sandstones presents three stages: weakening, stabilizing, and surging.

A case study on the stability of a big underground powerhouse cavern cut by an interlayer shear zone in the China Baihetan hydropower plant

Deep Underground Science and Engineering, EarlyView.
A 9‐year study on the deformation and stability problem of the large deep underground cavern in Baihetan power station was carried out. Abstract The big underground powerhouse cavern of the China Baihetan hydropower plant is 438 m long, 34 m wide, and 88.7 m high.

Analysis of squeezing‐induced failure in a water tunnel and measure of rehabilitation: A case study of Tishreen tunnel, Syria

Deep Underground Science and Engineering, EarlyView.
Different failure modes observed in Tishreen tunnel include Floor heave, wall spalling, crashing of slab, and lining convergence reaching the failure limit. Abstract Squeezing phenomena can lead to severe loads in deep tunnels, especially in the presence of a low ratio of surrounding rock strength to overburden pressure.
