With a certain actual lime-soil pile composite foundation project for background, the Finite Element Method (FEM) model of composite foundation was carried out by using the Drucker-Prager theory and ANSYS FEM procedure. By imitating the status of composite foundation under the construction load and analyzing the factors such as stress, settlement, stress ratio between pile and soil, carrying capacity of composite foundation with lime-soil pile has been gained. The conclusions offer some beneficial references to design and construction of actual projects.

This article mainly analyzes the bucket wheel stacker reclaimer slewing mechanism gear cracking. We put the flange as the research object. Through analysis of matrix composition and cracking gear macro fracture morphology, we can preliminarily determine the cracking mechanism and failure cause of the flange. Then, through the carrying capacity of gears calculation by the analytic method and the finite element method, we further identify the failure causes of the flange and put forward the reasonable and feasible solutions.

[ID] Pembangunan gedung mahasiswa pada kawasan Universitas Islam Riau merupakan bangunan bertingkat 4 yang berfungsi sebagai tempat sekretariat organisasikemahasiswaan, kondisi tanah pada lokasi pembangunanGedung Mahasiswa pada Kawasan Universitas Islam Riaudidapat pada titik sondir 1 pada yaitu sebesar 50 kg/cm2 Sedangkan pada titik sondir 2 yaitu sebesar 100 kg/cm2. Penelitian ini merumuskan masalah apakah daya dukung tiang bor (bored pile) pada bangunan gedung mahasiswa Kawasan Universitas Islam Riau aman terhadap beban aksial, beban lateral dan momen dengan memperhitungkan beban mati, beban hidup, beban angin dan beban gempa, serta Berapa besar penurunan dan defleksi horizontal yang terjadi dengan menggunakan bantuan software ETABS v.9, menghitung kuat dukung, penurunan dan defleksi horizontal dengan metode elemen hingga menggunakan PLAXIS 2D. Pembangunan gedung mahasiswa dikawasan Universitas Islam Riau Pekanbaru yang berlokasi dijalan Kaharuddin Nasution No.113 Marpoyan Damai-Pekanbaru Riau. Parameter tanah menggunakan data uji sondir dengan  kedalaman pondasi 12 m dan diameter 30 cm, Metode yang digunakan pada penelitian ini sesuai dengan tujuan penelitian dalam perhitungan daya dukung pondasi bored pile dan perpindahan yang terjadi dengan metode elemen hingga menggunakan PLAXIS 2D. Hasil perhitungan memperlihatkan bahwa kapasitas daya dukung aksial pada titik sondir 1 yaitu sebesar 323,072 kN dan kapasitas daya dukung aksial pada titik sondir 2 yaitu sebesar 432,823 kN sedangkan untuk daya dukung lateral pada titik sondir 1 didapat yaitu sebesar 125,016 kN, pada titik sondir 2 yaitu sebesar  190,703 kN dan penurunan pada titik sondir 1 yaitu 40,04 mm dan pada titik sondir 2 yaitu 25,69 mm sedangkan untuk defleksi horizontal pada titik sondir 1 yaitu 10,91 mm dan pada titik sondir 2 yaitu 6,81 mm. Jadi defleksi horizontal yang terjadi pada titik sondir 1 dan 2 belum memenuhi syarat yang di ijinkan. [EN] The construction of a student building in the Riau Islamic University area is a 4-storey building that serves as a place for student organization secretariat, soil conditions at the construction site. The Student Building in the Islamic University Area of ​​Riaud can be found at sondir 1 at 50 kg / cm2, whereas at sondir 2 is 100 kg / cm2. This study formulates the problem of whether the carrying capacity of bored piles in the buildings of the Riau Islamic University Region building is safe from axial loads, lateral loads and moments by calculating dead loads, live loads, wind loads and earthquake loads, and how much reduction and deflection horizontal that occurs using the help of ETABS v.9 software, calculates the horizontal bearing strength, decrease and deflection using the finite element method using PLAXIS 2D. The construction of a student building in the Riau Islamic University area of ​​Pekanbaru, located on the Kaharuddin Nasution street No.113 Marpoyan Damai-Pekanbaru Riau. Soil parameters using sondir test data with a foundation depth of 12 m and a diameter of 30 cm, the method used in this study is in accordance with the research objectives in calculating the carrying capacity of the bored pile foundation and displacement that occurs with the finite element method using PLAXIS 2D. The calculation results show that the axial carrying capacity at sondir point 1 is 323,072 kN and the axial carrying capacity at sondir point 2 is 432,823 kN while for lateral carrying capacity at sondir point 1 is 125,016 kN, at sondir 2 190,703 kN and decrease at sondir point 1 is 40,04 mm and at sondir point 2 is 25,69 mm while for horizontal deflection at sondir point 1 is 10.91 mm and at sondir point 2 is 6,81 mm. So the horizontal deflection that occurs at sondir 1 and 2 does not meet the permitted requirements.

Abstract.Under external loads, the continuously prefabricated slab of double-block ballastless track may crack easily. The cracks will reduce the durability and carrying capacity of the roadbed slab. Moreover, the cracks may also affect the use and safety of the double-block ballastless track during its service. When the roadbed slab crack, we should take some maintenance measures to maintain the normal use and durability of the double-block ballastless track. This paper based on the finite element method, established a beam-brick model for double-block ballastless track which has a through crack on the roadbed slab to analysis what kind of patching material is the most suitable when the most unfavorable loads act on the track. For this reason, we can provide theoretical basis for maintenance of double-block ballastless track .
