Land Sliding

Landslide is one of major issue that occurred during rainy season. This problem is straightforward and able to be prevented with installing reinforcement into the designated landslide location prior to sliding failure. It is effective due to the reinforcement cutting through failure plane, hence strengthen the soil body.  By and large, prior to land sliding, several indications are taken into place, such as soil cracking, structural cracking, vegetation movement, etc. By observing this event, one should be aware that further soil movement are very likely to follow afterwards. Consequently, safety precaution shall be taken. This paper presents one case study in Hambalang, Bogor, West Java, Indonesia. In this case, structural crackings are found in several places, especially at the poolside. These are appeared earlier this year, concurrently with very high intensity rainy season which is predicted to be the cause. Analysis is performed to check the current stability of the slope. The result is showing that the Safety Factor value is 1.181, below the allowable value of 1.5. Then, reinforcement is designed as a preventive measure. It is using retaining wall by employing bored pile coupled with sufficiently thick capping beam. From analysis, the safety factor is increased to 1.553 during critical condition. This value is above the criteria of 1.5 and concluded as a safe design. Structural capacity of bored pile is also designed. Accordingly, the retaining wall is constructed on site in final stage

The Stability

On the construction of green open space Jl. Kinibalu Banjarbaru There is a 6 meters tall slope beneath which the river is lined up during the rainy season and makes the slope exposed by water plus the absence of load or traffic on it make the pore figures on the land is large. Therefore, for protection reason, there is a soil alignment in the construction of soil retaining walls. The planned ground retaining wall type is cantilever and gabion. The stability analysis of the ground retaining walls is done manually and with the help of the Geoslope/W 2018 software. The value of the stability of the style against the bolsters, sliding, and carrying capacity of the soil using manual calculations for cantilever type and Netlon qualifies SNI 8460:2017. And for the overall stability calculation using Geoslope/W 2018 software obtained safety factor (SF) > 1.5. From the analysis, the design of planning can be used because it is safe against the dangers of avalanche.

abstract: This study evaluates load variations in instrumented prestressed ground anchors installed in a bored pile retaining wall system in sandy soil. Data were collected from instrumentation assembled in the bonded length of three anchors, which were monitored during pullout tests and during different construction phases of the retaining wall system. Instrumentation consisted of electrical resistance strain gauges positioned in five different sections along the bonded length. Skin friction distributions were obtained from the field load measurements. Results showed that the skin friction followed a non-uniform distribution along the anchor bonded length. The mobilized skin friction concentrated more intensely on the bonded length half closest to the unbonded length, while the other half of the bonded length developed very small skin friction. The contribution of the unbonded length skin friction to the overall anchor capacity was significant and this should be accounted for in the interpretation of routine anchor testing results. Displacements applied to the anchor head were sufficient to mobilize the ultimate skin friction on the unbonded length, but not on the bonded length. Performance of loading-unloading stages on the ground anchor intensified the transfer of load from the unbonded length to the bonded length. Long-term monitoring of the anchor after lock-off revealed that the load at the anchor bonded length followed a tendency to reduce with time and was not significantly influenced by the retaining wall construction phases.
