RISInfluence of the Size and Content of Quartz Sand on the Properties of Silicate-Membrane Slurry and the Performance of Filter Cake
Publisher: American Society of Civil Engineers
Abstract: Borehole wall stability is the key to the shield tunnel and horizontal directional drilling (HDD) under a sand-pebble layer. Borehole instability will lead to the collapse of the upper ground and damage to adjacent structures. ...
