Abstract
Abstract Soil having liquefaction potential in a load bearing region is stabilized by the placement of load supporting pile means in the region and the placement of water impervious means in the region, the water impervious means extending to a depth at least equal to that of the soil having liquefaction potential to facilitate dewatering of the region and to prevent the entry of ground water thereinto.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
148 words
In a region normally including a stratum of loose water bearing granular soil having liquefaction potential, a load supporting system comprising: load bearing means in said region extending to a depth at least to a load bearing level, endless wall means in said region extending to a depth at least equal to the depth of said stratum to confine that portion of said stratum above a load bearing level and within said wall means and to resist the flow of ground water into said stratum, and water removing means including means within said stratum confined by said endless wall means and extending to a depth near the bottom of the stratum for removing water from within the confines of said wall means substantially to dewater said soil to a degree sufficient to stabilize said soil having liquefaction potential thereby to provide additional support for said load bearing means.
Claim 2
Dependent Claim
148 words
In a region normally including a stratum of loose water bearing granular soil having liquefaction potential, a load supporting system comprising: load bearing means in said region extending to a depth at least to a load bearing level, endless wall means in said region extending to a depth at least equal to the depth of said stratum to confine that portion of said stratum above a load bearing level and within said wall means and to resist the flow of ground water into said stratum, and water removing means including means within said stratum confined by said endless wall means and extending to a depth near the bottom of the stratum for removing water from within the confines of said wall means substantially to dewater said soil to a degree sufficient to stabilize said soil having liquefaction potential thereby to provide additional support for said load bearing means.
Claim 3
Dependent Claim
18 words
A structure according to claim 1, including means monitoring the level or quantity of water in said region.
Claim 4
Dependent Claim
25 words
A structure according to claim 1, wherein said endless wall means extend into a water impermeable stratum below said stratum of soil having liquefaction potential.
