It introduced the purpose and the type of the shield grouting briefly. On the assumption that other parameters are identical
through the example
it used finite element program GTS to simulate the situations considering or not considering hardening process on shield grouting .The main results are as follows:with the advancing of the shield tunneling
because of long-term consolidation effect by grouting
the surface will produce further settlement. With the effect of grout hardening fully considered
sclerosis is monitored to control further settlement
which is an effective means of controlling strata settlement.
