The subsurface conditions and <br>nearby existing structures generally decide whether the diaphragm wall will be cantilever or propped. Here is <br>a case study on a diaphragm wall for Qatar Industrial Manufacturing Company Building that comprises of 4 <br>basements, ground floor, mezzanine, podium, and 38 floors. The planned excavation depth for the four <br>basements was 15.95m. The subsurface ground consisted of made ground/fill material, Caprock, Simsima <br>Limestone, Midra Shale and Rus formation. Plaxis 2D software was used to analyze the diaphragm wall. The <br>analysis results showed that ground anchors were required to limit the deflection of the wall within the <br>allowable deflection. Moreover, due to unavailability of foundation details for neighbor building, the ground <br>anchor option was dropped, and inclined steel struts were considered, only in that section. As the inclined steel <br>struts were supported by pile foundation, therefore lateral load analysis was performed through LPile software.<br>Staad Pro. software was also used to analyze the waler beams. The target points at the top of the diaphragm <br>wall were monitored through Total Station equipment to measure the horizontal deflection of the wall.</p> ER -
