Analytical Research of Vertical Load Test on Bore Pile

Abstract: The vertical lode test is conducted on RCC bore pile this test is conducted as per the guidelines of IS 2911 part 4 respectively. This test is conducted on “Perstorp site which is located in dist. -Bharuch Gujrat. In this region the Strata of soil is soft aquifer hence to carry heavy structural load, pile foundation is best solution. The experimental study is carries out on 10 meter length of Bore pile of 500mm in diameter of loading area of 283.5 sq.cm. This paper is based on experimental study on bore pile due to vertical loading condition and expressing the behaviour of pile under the vertical incremental loading condition. And in this paper we follow the approach of analytical and experimental.

Pile Integrity

Abstract: The integrity test is conducted on RCC bore pile this test is conducted as per the guidelines of ASTM D5882 respectively. This test is conducted on “Perstorp site which is located in dis -Bharuch Gujrat. In this region the Strata of soil is soft aquifer hence to carry heavy structural load, pile foundation is best solution. The experimental study is carries out on 20 meter length of Bore pile of 600mm in diameter. This paper is based on experimental study on bore pile due to assess the pile integrity for potential problem like cross section change, honeycombing, concrete quality, continuity etc.

Permafrost Regions

Through conducting load test on reinforced concrete piles of the bridge in Kunlun Pass Basin, the research is mainly about pile foundation bearing capacity on permafrost regions. The paper expounds the fundamental of pile vertical load test and the loading method. Through analyzing the test data, what can be concluded is that it can be close to actual working condition of piles when pile load test is conducted on permafrost regions. Meanwhile, reference data is provided for future bridge projects in the application of pile on permafrost regions.

Load Tests

The effects of vertical load on the lateral resistance of single piles were initially reviewed to facilitate the interpretation of the test results of pile groups. Then, 18 different lateral load tests were carried out in the centrifuge on the 3 × 3 and the 4 × 4 fixed-head battered pile groups to investigate the effects of vertical load on the group lateral resistance. Vertical dead loads ranging from approximately 20 to 80% of the vertical ultimate group capacity Puv were applied. Based on these tests, the effects of vertical dead load on the lateral resistance of the battered pile groups are found to depend on pile arrangement, pile inclination, and soil density. The lateral resistances of the 3 × 3 pile groups do not appear to vary considerably with the vertical dead loads in the range of the vertical loads studied. For the 4 × 4 pile groups however, the lateral resistances at vertical loads of approximately 50 and 80% Puv may be 26-29% and even 40% higher than that at the 20% Puv dead load. It may be inferred that designs based on standard lateral load tests with small vertical dead loads would be on the safe side. Three mechanisms for vertical load effects are discussed in terms of axial tension and compression failures, influence of pile inclination, and initial subgrade reaction caused by vertical loading. Preliminary numerical analyses are also performed to simulate the responses of some of the battered pile groups.Key words: pile group, battered pile, lateral resistance, load test, pile-soil interaction, centrifuge test.
