yang berfungsi</span><span style="color: black; font-family: "Times New Roman","serif"; font-size: 16.0pt; mso-fareast-font-family: "Times New Roman"; mso-fareast-language: IN;">menyalurkan beban dari struktur diatasnya ke lapisan tanah pendukung.
Pondasi<span style="letter-spacing: 1.5pt;">sendiri jenisnya ada bermacam -
macam. Penentuan jenis pondasi biasanya</span><span style="letter-spacing: .75pt;">dipengaruhi
keadaan tanah disekitar bangunan atau pun jenis beban bangunan</span>itu
sendiri. Jika ingin Tahu lebih dalam lagi tentang pondasi<span style="letter-spacing: 1.5pt;">Pondasi merupakan bagian dari struktur yang
berfungsi meneruskan</span><span style="letter-spacing: .75pt;">beban menuju
lapisan tanah pendukung dibawahnya. Dalam struktur apapun,</span><span style="letter-spacing: 1.5pt;">beban yang terjadi baik yang disebabkan oleh berat
sendiri ataupun akibat</span>beban rencana harus disalurkan ke dalam suatu
lapisan pendukung dalam hal ini<span style="letter-spacing: 2.25pt;">adalah tanah
yang ada di bawah struktur tersebut. Banyak faktor dalam</span><span style="letter-spacing: .75pt;">pemilihan jenis pondasi, faktor tersebut antara
lain beban yang direncanakan</span>bekerja, jenis lapisan tanah dan faktor non
teknis seperti biaya konstruksi, waktukonstruksi. Pemilihan jenis pondasi yang
digunakan sangat berpengaruh kepada<span style="letter-spacing: 1.5pt;">keamanan
struktur yang berada diatas pondasi tersebut. Jenis pondasi yang</span><span style="letter-spacing: .75pt;">dipilih harus mampu menjamin kedudukan struktur
terhadap semua gaya yang</span><span style="letter-spacing: 1.5pt;">bekerja.
Selain itu, tanah pendukungnya harus mempunyai kapasitas daya</span><span style="letter-spacing: .75pt;">dukung yang cukup untuk memikul beban yang bekerja
sehingga tidak terjadikeruntuhan. Dalam kasus tertentu, apabila sudah tidak
memungkinkan untuk</span>menggunakan pondasi dangkal, maka digunakan pondasi
dalam. Pondasi dalam<span style="letter-spacing: 1.5pt;">yang sering dipakai
adalah pondasi tiang pancang. Menurut Bowles (1984),pondasi tiang pancang
banyak digunakan pada struktur gedung tinggi yang</span>mendapat beban lateral
dan aksial. Pondasi jenis ini juga banyak digunakan padastruktur yang dibangun
pada tanah mengembang (expansive soil). Daya dukung<span style="letter-spacing: 2.25pt;">tiang pancang yang diperoleh dari skin friction dapat diaplikasikan
untukmenahan gaya uplift yang terjadi. Faktor erosi pada sungai juga menjadi</span>pertimbangan
penggunaan tiang pancang pada jembatan.</span><br />
