Through the model test system

quantiftative research on the influence of change of soil strata and water content ratio on the strength of wet jetting piles was carried out. After contrasting the unconfined compression strength under different soil strata and water content ratio

two conclusions were found out as follow. One is that strength of wet jetting piles in clay strata is larger than in silty soil strata

main reason of which is that cement serosity soil grain and water have stronger ion exchange aggregation and pozzolanic reaction. Another that water content ratio of foundation have prominent influence on the strength of wet jetting piles

and there exists a best water content ratio

under which

wet jetting piles have a maximum strength.
