ABSTRAKRencana pembangunan pembangkit listrik tenaga surya di bali. Karena berada lokasi bukit tinggi dekat laut yang dimana memiliki hembusan angin cukup kuat sehingga memengaruhi aksial tekan dan tarik. Oleh karena itu alternatif untuk menahan beban tarik yaitu menggunakan fondasi Helical pile penempatanya bebatuan tanah Limestone. Dalam pemodelan helical divariasikan spasi helix nya 0,1 m; 0...

This paper presents the results of a geological engineering investigation in form rock mass characterization at Jlantah Dam Intake Tunnel. The study was carried out through technical mapping, core drill evaluation and supported by laboratory test data. determination classification research site has been using Rock Mass Rating (RMR) method, but it is necessary to use another method that more sui...

The Geological Strength Index (GSI) system is the basis of parameters used in Hoek-Brown failure criterion for rock mass strength estimation. author tested this and here suggests a modified GSI called Index-slope (GSIslope). combines two different existing approaches: Slope Mass Rating (SMR). purpose GSIslope to allow engineering geologists quickly evaluate stability natural excavated slopes or...

The bearing capacity factors for a rough strip footing placed on rock media, which is subjected to pseudo-static horizontal earthquake body forces, have been determined using the lower bound finite element limit analysis in conjunction with power cone programming (PCP). mass assumed follow generalized Hoek-Brown (GHB) yield criterion. No assumption needs be made smoothen GHB criterion and conve...

Rock failure during tunnel excavation is still a matter of concern. The influence groundwater generally taken into account along discontinuities or in “soil-like” formations. However, brittle saturated porous rocks can be subject to undrained conditions excavation. Negative effective stresses develop close the boundary. This study aims at identifying limit pore pressure rock around tunnel, whic...

Modern technology has been used to build tunnels in recent years by means of drilling machines (TBM) that were used for civil engineering work in large cities to reduce the harmful effects of spending on the surface of the earth significantly. To build the tunnel, numerical modeling was used on the basis of the finite element method to predict stress behavior during the tunnel construction proc...
