On the mechanical analysis of cracks on side walls in open-cut metro station and its control measures

Combined with the specific projects practices,it introduces the no-seam construction technology of over length concrete structure,represents the integral technology of setting the expand late poured band to strength the concrete moisture retention,maintenance and structure,so to the no-seam construction in motherboard pf underground and the side walls.

The paper studied the hydraulic characteristics of the side wall aerator by using the numerical simulation.

Analysis on the cracks of sidewall in the cavity of human prevented project of Weihe river tunnel and the management;

Hydraulic characteristics along the sidewall of a sluice downstream of a sudden lateral enlargement and vertical drop;

Experimental study on air entrainment to alleviate cavitations for downstream sidewalls of ogee-section in spillway tunnel;

The technological research on soliding slope of poor concrete frontier wall breaker strip of a reservoir;

Building or Destroying Frontier Wall and the Miao Society During the Ming and Qing Period;

Analysis on sidewall deformation in TGP s ship lock;

Application of sidewall extrusion method to concrete face slab dam construction;

Based on an analysis of causes of cavitation damages to the downstream at the end of ogee section in the spillway tunnel of open channel,it is pointed out that the aeration measure for sidewall protection nearby the downstream of ogee section should be paid much attention in aerator design.
