Pile foundations are intended to hold both vertical and horizontal loads. Pile foundation design must take into account the lateral carrying capacity, especially on those that experience large lateral force. In fact, vertical load and horizontal load work simultaneously on the piles. Therefore it is necessary to look at the effect of the vertical load towards the carrying capacity the lateral piles. This study uses several models of pile foundation. The inclination of which the models are varied pile into three kinds, namely the inclination of 0° (upright pole), the inclination of 15o and 30o. While the vertical load is varied into four kinds, namely 0 kg load (no-load), 0,5 kg, 1 kg and 2 kg.The tests were done by inflicting horizontal loading on each variation of test models. Load test results are interpreted using the Tangent Intersection, Davisson method, the Chin method, and Mazurkiewicz method to get the ultimate lateral bearing capacity. The interpretation result of Tangent Intersection method showed the tendency to increase the carrying capacity of the lateral pile models as the vertical load increase. While the results of interpretation met of Chin method, generally showed the same trend. However, the interpretation of Davisson method and Mazurkiewicz methods did not indicate any trend of increasing the lateral carrying capacity with the increase of vertical load. The relationship between the carrying capacity and the inclination of the pile, from the interpretation of the data of load test results, did not indicate a trend of increasing the lateral carrying capacity of the pile models as the inclination of the piles increase.Keywords : pile foundation, model, lateral, vertical load

Abstrak. Pembangunan konstruksi di atas tanah gambut mempunyai banyak masalah, diantaranya adalah daya dukung tanah yang rendah dan penurunan yang besar. Penggunaan kombinasi grid bambu dan geotekstil diharapkan akan dapat mengatasi masalah tersebut. Penelitian ini bertujuan mengetahui hubungan antara kapasitas daya dukung dengan variasi kedalaman letak perkuatan, lebar perkuatan, spasi antara grid bambu dan geotekstil, dan sudut penyebaran beban. Perbedaan daya dukung antara tanah tanpa perkuatan dengan menggunakan perkuatan dinyatakan dalam Bearing Capacity Ratio (BCR). Dari studi model di laboratorium diperoleh hasil BCR maksimum sebesar 4,32 pada rasio L/B, d/B, dan s/B berturut-turut adalah 3, 0,25 dan 0,5. Sudut penyebaran beban maksimum sebesar 78,79Â° pada L/B dan d/B (B adalah lebar pondasi) berturut-turut adalah 4 dan 0,25. Peningkatan BCR dan sudut penyaluran beban sebanding dengan penambahan dimensi perkuatan dan berbanding terbalik dengan jarak perkuatan dari dasar pondasi. Abstract. The construction on peat soil have many problems, Two significant problems are low bearing capacity and high construction settlement. The usage of grid bamboo and geotextile as a composite system is expected to overcome those problems. The purpose of this research is to check the relationship of bearing capacity with depth of the reinforcement layer, width reinforcement layer and spacing of reinforcement layers between of grid bamboo and geotextile, and to the angle of stresses distribution. The difference of the bearing capacity between unreinforced soils and reinforced soils referred as Bearing Capacity Ratio (BCR). From study model at laboratory the result indicate that maximum BCR is 4.32 at ratio L/B, d/B and s/B are increasing 3, 0.25, and 0.5. Maximum the angle of distribution is 78.79Â° at L/B and d/B (B is width of footing) are increasing 4 and 0.25. The increasing of BCR and angle of stress distribution is proportional by the increasing of reinforcement dimension and it diversely correlated with depth of reinforcement.

In practice, the design of pavement is commonly based on the California Bearing Ratio (CBR) test. This research was performed to study the local correlation between Hand Cone Penetrometer (HCP) tests to the field CBR value. The local correlation is determined based on comparisons of HCP and CBR test results for the soil with same density which have been taken from several locations in Pekanbaru City, Indonesia. It was found that there is an approximate linear relation in log scale between HCP test results to CBR values for a certain density of soil. Correlation for HCP and density to CBR has been put forward for the local correlation between those two values. Verification of the formula has shown that the correlation can be used relatively accurate for predicting the field CBR values from the HCP test for in-organic soils. For organic soil, the formula needs to be further researched.

A Tenayan Raya subdistrict is an area where there is an adequate thick of clay layer. This condition is seen during rain that the soil become softer, while in dry conditions there are many cracks on that soil. In case, it can cause some damages to the building due to the tilt of the building's foundation as an effect of shrinkage soil. Tenayan Raya also known as a brick production area. The brick production process may generate ash as a waste of brick kilns which has not been utilized optimally. This study aims to utilize brick ash as an additive material to improve clay properties in term of reducing its shrinkage feature. A certain amount of brick ash were mixed to clay soil and lime also were two added as a companion of a stabilizing agent. Some variation properties of two additive materials were applied in the sample of UCS and CBR tests. The effect of curing and soaking time was also be checked in term of UCS and CBR value changed. Based on properties tests, the clay soil classified standard. The mixture of 80% clay + 10% lime + 10% brick ash, in OMC condition, has the maximum of UCS and CBR laboratory test value. Curing and soaking time also has a significant contribution in increasing UCS and CBR value. The maximum value of both tests was reached at day 7th of curing and soaking time.Keywords : Clay, Swelling, Stabilization, Lime, Brick ash, Soil bearing capacity
