Buihomau-Daudere bridge is a civil building located in Iolomar Sub district Lautem
Regency. With the existence of this bridge, it is expected to enable transportation
current and local society economic. In the part of bridge oprit side to Daudere has
occurred landslide or damage, therefore, it should be done renovation and stability
improvement. Each stake foundation is one of general foundation types utilized. The
function of this foundation is to canalize hard land layer structure that has high
support capacity which is its location is deep enough from the land surface.
The land observation data obtained from Dili Public Works Department, among them were sondir
CPT and SPT data, based on the existing data, it was estimated the land type in the location is
various from soft sand to very hard land. In analyzing stake pole support capacity utilized some
calculation methods such as the methods of S c h n e r tma n n a n d Not t i n g h am, Mayerhof,
Terzaghy and Peck
Of the calculation result, stake pole support capacity were the methods of S c h n e r tma n n a n d
No t t i n g h am, Qu = 3 3 9 . 4 5 kN, Ma y e r h o f me t h o d s Qu = 257 kN, Terzaghy and
Peck, Qu = 205.56 kN. By using above, stake pole support capacity is more secure if it used the
smallest value, which were Terzaghy and Peck,Qu = 205.56 kN method. For the pole efficiency, it
utilized approach suggested with Converse-Laberre Formula, Eg = 0.85<1, and block collapse =
4.07> 2. The comparison between manual calculation and Plaxis program result v. 8.2, pole
deflection on manual calculation = 0.009 m and tht result of running program Plaxis result v.8.2 =
0.01 m.
