Abstract

Metode pengukuran dan analisis multichannel analysis of surface wave (MASW) mampu digunakan untuk estimasi kurva dispersi mode jamak. Metode ini diterapkan untuk mengetahui kecepatan gelombang geser bawah permukaan tanggul LUSI melalui proses inversi. Proses inversi ini dilakukan menggunakan algoritma regressive-regressive particle swarm optimization (RRPSO). Analisis mode dasar dari kurva dispersi pada beberapa lintasan di tanggul LUSI menunjukkan bahwa pada tanggul P76- P77 ditemukan anomali Patahan Watukosek pada kedalaman sekitar 40 meter, dan juga pada tanggul P79-P82 ditemukan anomali yang memiliki potensi untuk menyebabkan penurunan tanah. ================================================================================================================== The method and analysis of multichannel analysis of surface wave (MASW) is able to estimate the dispersion curves. This method is applied to determine the shear wave velocity of subsurface embankment LUSI through an inversion process. This inversion process is using an algorithm regressive-regressive particle swarm optimization (RR-PSO). Analysis of the basic mode of the dispersion curve on some path on the LUSI embankment show that in P76-P77 found anomalies Watukosek Fault at a depth of about 40 meters,and also on the embankment P79-P82 found anomalies which have the potential for causing subsidence.
