A brief method to identify weak layer or slip surface existing in a slope is presented by analyzing vibrating signals induced by blasting.

In this paper, The main idea is the applicatinn of timeber pile in weak layer of building foundation for consolidation and the methods of analysis of bearing capacity and settlement.

128mm,which meet the design requirement;④The vibroroller compaction in large thickness cushion for ground treatment of weak layer has good results.

In the complex soft layer contained large quantity of living rubbish,construction on sinking tubular pile with conven-tional method,will lead on to reduce tube diameter.

How to infer if a soft stratum lies below the bearing stratum supporting a rock-socked pile.

On soft interlayer affecting roadway stabilization in roof

The authors calculated the reaction spectra of seismic waves that came from the practical soil layer at different depths and, by modifying the practical soil layer parameters and analyzing the spectra of seismic waves in varied depths of the soil layer and the soft interlayers, drew some significant conclusions.

This paper introduces the stable analysis calculation for the sluice chamber motherboard slide along rock foundation and soft interlayer,under non earthquake condition for the spillway chamber of Guanhe reservoir,and resist earthquake check computation.
