Permanent Slope Protection in Highly Seismic and Landslide-Prone Area Using Multi-Level Anchored Aligned Pile Wall
This paper presents the innovative analysis, design and construction of permanent slope protection in highly seismic and landslide prone areas. The project scope of work consisted of creating a stable, large horizontal bench along a steep and long slope at the toe of an existing industrial complex, suitable for the construction site of a new industrial building complex 50 meters high. Several high slopes had to be developed, one after the other, and permanently stabilized to generate a safe and stable building site. Originally, the contract called for an Anchored Diaphragm Wall (ADW) to support permanently the vertical slope. However, during an early stage of construction, discrepancies on the Owner-supplied Project Site Soil and Geological Conditions were discovered that necessitated design amendment. Anchored Aligned Pile Wall (AAPW) with Pervious Piles (PP) in between to serve as vertical draining elements was finally adopted to retain the 18-meter high vertical slope, thus allowing the construction of the new building complex on the slope, free from problems of high earth and hydrostatic pressures and external surcharges. The ultimate purpose of the project was to provide local and global stability of the whole building complex during construction and ultimate service that required a design horizontal ground acceleration of 0.4g with performance objective of Immediate Occupancy after the earthquake. This paper describes the design concept of the retaining wall systems, the problems encountered due to "change of site conditions", and the solutions designed and developed to cope with the actual site conditions.
