Abstract

A soil retaining system combining flat sheet pile walls in an open cell configuration includes integral soil anchors to provide an earth retaining system. A method of designing and installing a soil retaining system with an open sheet pile cell structure having integral soil anchors. The method includes, inter alia, calculating soil forces by taking into account material strength of sheet pile, soil friction against the sheet pile in combination with the strength of the integral soil anchor, selecting sheet pile size and length based on soil forces calculation; and installation of sheet pile to form a soil retaining system. The integral soil anchors serve to provide higher load resistance to the earth retaining system.

Claims

1. A method of designing and installing a soil retaining system with an open sheet pile cell structure having integral soil anchors comprising;

calculating the frictional resistance force of the sheet pile against the soil;

calculating the compressive resistance force of the integral soil anchor against the soil;

selecting the sheet pile size and length based upon the combination of the frictional resistance force and the compression resistance force; and

installating the sheet pile to form a soil retaining system.

2. The method of claim 1 further comprising calculating a resistance force of an interconnected end anchor.

3. The method of claim 1 wherein calculating the compressive resistance force increases the overall resistance force of the soil retaining system by a factor of 1.4 or greater.

4. The method of claim 1 wherein the sheet pile are P32 standard sheets.

5. The method of claim 1 further comprising backfilling the soil retaining system.

6. The method of claim 5 further including burying utilities in the backfill.

7. The method of claim 1 wherein calculating a compressive force includes a bearing and pull-out resistance force at an angle to the face of the sheet pile.

8. The method of claim 1 further including installing face ladders, mooring systems, or fender systems on a front face of the soil retaining system.

9. A method of designing a soil retaining system, comprising;

calculating frictional resistance force of a sheet pile against the soil;

calculating bearing resistance force of a soil anchor integral with the sheet pile against the soil;

selecting the sheet pile size and length based upon the combination of the frictional resistance forces and the bearing resistance forces; and

using the sheet pile to form a soil retaining system.
