This book was released on 1987 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prototype test data on the hydraulic performance of the standard US Army Corps of Engineers spillway crest at Chief Joseph Dam were obtained following structural modifications to the project required to raise the pool for expansion of hydropower capabilities. These data were correlated with comparable data obtained in model studies of the dam and compared with the data of earlier prototype tests prior to the pool raise. The prototype data consisted of spillway pressure profiles obtained with piezometers, pressure fluctuations indicated by pressure cells embedded in the spillway crest, and vibrations monitored by accelerometers bonded to the trunnion bridge and access gallery floor. The data were obtained at heads of 1.31 and 1.21 times the design head H sub d is one gate bay at full and partial gate openings. Good correlation was found between the model and prototype spillway data for the increased head design. The negative pressures in the prototype generally agreed with those predicted in the model. These negative pressures exceeded those obtained in earlier prototype tests primarily due to the increased pool elevation and subsequent higher heads. No significant pressure fluctuations that could cause resonance in the structure were found for any flow condition. No significant vibrations or displacements were evident from the acceleration measurements.

Hydraulic Model Investigation written by ARMY ENGINEER DIV NORTH PACIFIC BONNEVILLE OR DIV HYDRAULIC LAB. and published by . This book was released on 1983 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chief Joseph Dam project was modified in the late 1970's to accommodate a 10-foot pool raise. Modification included raising and widening of the spillway piers. Inspection of the piers reconstructed early in the modification contract revealed that the as-built pier shape in the vicinity of the stoplog slots was considerably out of tolerance form the design shape. The as-built shape raised concern over potential for cavitation resulting from localized areas of low pressure near the stoplog slots. a 1:30 scale model was used to study the pressure regime in the area of the stoplog slot for design shape three as-built shapes, and three alternative shapes to evaluate limiting criteria for correction of the misalignment if required. Study results indicated that during spillway design flood conditions pressures on the as-built piers tested could result in cavitational damage. During the later stages of construction, the piers conformed closely to the design shape, and the Seattle District decided that modification of the earlier reconstructed piers was not warranted.

This book was released on 1988 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Report was prepared in accordance with ER 1110-1-1801, dated 15 December 1981, which requires as-built foundation reports for major construction projects. Purpose of this report is to ensure the preservation for future use of complete records of foundation conditions and treatment for the powerhouse additional units 21-27; post construction instrumentation, drain hole drilling, and rock contour maps for the spillway, nonoverflow, intake and closure monoliths; and for the left and right abutment exploration and instrumentation program. In general, the foundations of the dam and powerhouse are of excellent quality. (FR).
