Telah dilakukan penelitian tentang Uji Sondir di Kabupaten Lima Puluh Kota tepatnya di Kecamatan Harau Pada Tahun 2021. Penelitian ini bertujuan untuk mendapatkan daya dukung tanah serta jenis pondasi yang cocok di titik lokasi penelitian sehingga terhindar dari kegagalan struktur (bangunan roboh/runtuh). Metode penyelidikan tanah dilakukan dengan cara pengujian langsung di lapangan menggunakan alat sondir. Data sekunder didapat dari beberapa kajian literatur. Data primer didapat dari hasil sondir di dua titik lokasi yang telah ditentukan. Analisis data menggunakan dua parameter pada setiap kedalaman yaitu Nilai Perlawanan Konus (NK) dalam satuan kg/cm2, Jumlah Hambatan Pelekat (JHP) dalam satuan kg/cm. Kedua parameter diatas dicatat untuk setiap interval 20 cm sampai kedalaman dimana didapatkan nilai  NK ≥ 155 kg / cm2, dengan batasan kedalaman maksimum 10  m dari muka tanah setempat. Hasil penelitian sondir diukur dari elevasi ± 0.00 (muka tanah setempat) pada titik 1 NK ³ 155 kg/cm2 didapat pada posisi kedalaman – 10.00 m dengan nilai TFR 410 kg/cm. Sedangkan pada titik 2 didapat pada posisi kedalaman – 6.00 m dengan nilai TFR 248 kg/cm. Berdasarkan perhitungan daya dukung tanah maka jenis pondasi yang cocok untuk perencanaan pembangunan proyek tersebut adalah pondasi dalam (bore pile).

The Dead

Foundation is the lower structure of the building located below the ground that has the function to bear the load of the building. The building has been standing for ± 5 years and the slope of the building is ± 1-20. The authors analyzed soil bearing capacity, settlement and the slope of the building and the possibility of repairing the building for reuse. In 1 pile cap there are 4 bore piles with a depth of 6m-12m, because the pile cap data is not obtained then the size and thickness is assumed and the soil data used is secondary data without lab data derived from soil data in locations adjacent to the building site that is ±100m from the building site. After the analysis, soil bearing capacity is not strong to bear the dead load of the building when using a foundation with a depth of 6m-12m, there is a possibility that the foundation used is not suitable and there is a reduction in the load of the building due to the presence of other buildings that are adjacent to the building in the analysis resulting in a considerable decrease and slope of the building.Fondasi adalah struktur bagian bawah bangunan yang terletak di bawah permukaan tanah yang mempunyai fungsi memikul beban bangunan. Bangunan ini sudah berdiri selama ± 5 tahun dan  kemiringan bangunan sebesar ± 1-20. Penulis menganalisis daya dukung tanah, penurunan tanah dan kemiringan bangunan dan kemungkinan memperbaiki bangunan agar dapat digunakan kembali. Pada 1 pile cap terdapat 4 buah bore pile dengan kedalaman 6m–12m, karena data pile cap  tidak diperoleh maka ukuran dan ketebalannya diasumsikan dan data tanah yang digunakan adalah data sekunder tanpa data lab yang berasal dari data tanah di lokasi berdekatan dengan lokasi bangunan yang berjarak ±100m dari lokasi bangunan. Setelah di analisis, daya dukung tanah tidak kuat untuk menahan beban mati bangunan bila menggunakan fondasi dengan kedalaman 6m–12m dan ada kemungkinan fondasi yang digunakan tidak sesuai dan terjadi reduksi beban bangunan karena adanya bangunan lain yang berdempetan dengan bangunan yang di analisis sehingga mengakibatkan penurunan dan kemiringan bangunan yang cukup besar.

Many cast-in-site bore pile have broken pile because of collapsing in wall of holl. Based on the principle of mechanics, a new combination approach was proposed for dealing with the broken pile. The approach is displacing the soil in the pile by cement paste and increasing the height and the steal ratio of the top beam which is on the defect pile. Using the finite element software, we have set up the analysis model of the approach, which helps to demonstrate the rationality of this method. This method can be referenced by the reinforcement and maintenance of the bridges.
